So since I know you aren't arguing with a good faith I took time to analyze every. single. FGA. in those links. No contact also includes not landing in his shooting space:
vs WIZARDS:1. Harden barrels right into the chest of the defender. There is very light contact but defender is vertical and doesn't extend his arms sideways. This is classic no call because there is no call. These aren't called 9/10 times in the NBA.
2. Very similar play, if you want to call literally the smallest things be my guest.
3. Stepback brick. No contact what so ever.
4. Driving layup no contact at all. Made it
5. Driving layup. Bertans goes vertical and there is no contact.. misses
6. Another Driving layups. Zero contact.
7. Driving layup. No contact
8. Stepback brick. Zero contact.
9. Driving layup. Basically no contact. Just Harden'esque weird stop and swing ball around but never hits defender with his arms or body. Miss
10. Catch and shoot 3. BRICK no contact
11. another BRICK 3. No contact
12. Flat footed brick 3. NO CONTACT...?!?!?!? What is the point of moaning if all he does is this?
13. Stepback 3. Defender lands in his space and is correctly called
14. Another driving layup. Defender gives up because he doesn't want to get a foul called on him. Harden misses
15. 3 pointer. No contact. Brick
16. 3 pointed BRICK. no contact....
17. Not shown on the video so who knows..
Conclusion is Harden was very passive and just missing 3 point shots. Wizards also played very well and went vertical or didn't jump at all on his layups. There was maybe 1 missed call under last year's rules but considering rules this year there was no missed calls.
HORNETS:1. Screen. 3 Pointer. Basically no real contest either. Just bricks it.
2. Tear drop. Zero contest. Misses
3. Guy just hangs on his side there is no real contact. Harden makes the shot.
4. Loong 3 point shot. made. Zero contact
5. Mildly contested 3 point shot. Harden instantly acts like he was touched which probably resulted the miss. There was 0 Contact. BRICK
6. Another Harden driving layup. Basically throw arms into defender's face. But there is no contact and Harden misses. Maybe he should try make the shot instead of fishing for fouls when defender isn't really even that close to him?
7. Stepback 3. Contested, makes it.
8. Same play. Different spot. BRICK
9. Driving layup. I see zero contact. Both defenders have arms up not trying to foul. Phantom call and this is very questionable and I would bet anyone but Harden wouldn't get this call at all. He makes it though.
10. Harden misses tear drop. There wasn't any contact.
11. Another stepback 3.... You see the pattern here? And of course it is a no contact BRICK!!!
12. These type of plays are always questionable but 9/10 times these doesn't get called. Harden makes teardrop and after shot is halfway through he lands into Plumlee who is waiting him in his vertical position. I think all after plays are pretty much no calls these days. Harden makes the shot so that's something...
13. Step back 3... We know already... BRICK (no contact obviously)
14. Bridges challenges vertical (perfect vertical challenge) Harden misses.
15. Putback from the previous play. He makes it, no contact
16. Another stepback 3... However this time something new! It doesn't even hit the rim! No contact obviously...
So Hornets played him well. Basically didn't foul him at all in the clips showed here. Absolutely no issues here Harden just bricking 3 pointers.... If you want fouls maybe don't shoot step back 3s?
Sixers.. This is getting old...
1. Stepback 3 pointer. Brick. Considering ref is literally next to them watching his feet Embiid doesn't land close enough for it to be considered Harden's space, Harden just flops down. Absolutely should never be called and isn't called here.
2. Driving layup. Makes it. No contact at all.
3. Catch and shoot 3 brick. no contact..
4. Floater no contact. Makes it
5. This is questionable bump but very light. This is 50/50 play in NBA but this year nobody is getting benefit of this call.
6. Another floater. Misses. No contact.
7. Stepback. Makes it. No contact
8. Floater. No contact. misses.
9. Stepback. makes it. no contact.
10. Floater. Just wide open miss.
11. Harden takes offensive rebound. Actually fouls defender by shoving him with his forearm to clear out the space for rebound and makes the shot. Gets away with the murder.
12. Typical Harden in traffic drive. Put ball into defender's face. There is no contact but Maxey perfectly backs down and in process basically almost blocks the shot. But Harden rolls it in regardless.
13. Embiid blocks harden. There is no contact.
14. Curry with aggressive defense but just in time pulls hand away from Harden foul baiting. No contact. Bricked 3.
15. Wide open 3. Makes it
16. Wild out of control drive. Harden misses it and tries to bait for fouls even though there was really nobody there to contest him, Drummond late to rotate.
17. corner 3. Wide open miss.
Already hating myself for putting up with this garbage... Makes me think you are the one who never watched his games... There was one play which was 50/50. Almost all of these ones were no defenders nearby him.
Bucks1. Wide open 3. Brick
2. Another brick 3. Contested by Giannis and loser Harden tries to push him from back on Giannis dunk after Harden brick...
3. This is questionable call. Holiday is inside the restricted area. Goes vertical and mass of Harden just moves him away. Made the shot. This could've easily been a foul.
4. Floater. Made. No contact.
5. Dribble happy 3 pointed. Made it. No contact
6. Stepback 3 with a twist of a flop. Made it. Zero contact.
7. Another stepback 3. Made it. No contact
8. Stepback 3. Brick. No contact
9. Floater. Wide open. Miss.
10. Same play. No contact. Miss.
11. Rebounds the miss. Misses the wide open putback. No contact
12. 2nd offensive rebound. Thannes blocks him. 0 contact
13. Stepback flop. No contact. Made it.
14. 3 pointer. Miss. No contact.
15. Layup. Absolutely no contact apart of Harden trying to fish for it and flailing his arms.
16. Harden blocked. No contact. Miss
Twolves:1. Layup. No contact. MIsses
2. This could've been foul last year. Not called this year. Nobody is getting this.
3. Makes layup. No contact to warrant a whistle.
4. stepback 3. made it. no contact
5. Wide open 3. Miss.
6. Refs didn't call offensive foul push on the drive. Misses the shot
7. stepback 3. Miss. No contact
So the conclusion is. He is just bricking stepback 3s like no tomorrow from the eye test. This is also supported by his stats of shooting poor 32% from the 3 pointer. Defenders are just contesting him and not jumping into him. They are also very well going vertical (like Hornets and Wizards) and not fouling him...
This is an absolute nothing burger and as said makes me question if you have watched these games at all when you call out others. The conclusion is either no or through extremely biased lense. Harden have had 3-4 questionable calls all season long where he didn't get benefit of the whistle. This is happening to literally to everyone. Westbrook have had almost 10 of such calls where he absolutely crashes on his butt after the play with heavy hacking of his arms and no calls. These harden no calls were very slight bumps at the best and nothing to be warrant massive outrage. He just needs to be more aggressive if he wants fouls to be called... Almost 50% of Harden's shots this year come from the 3 point shots and while he has had similar shot charts before his inside scoring has taken almost 10% usage drop. So he isn't driving as much as he has in the past.
