I and I'm sure most mods agree that just like in "real life" racial and homophobic slurs are among the lowest of the low.
If the policies got too specific, they could go on for pages and pages. A balance has to be struck between being clear, and having an appropriately short length so that you lose the fewest number of posters halfway through.
The items you mentioned fall well into any of these from the policies:
1b. Members should post in a way that is respectful of other users. This applies to ALL users, regardless of post count, forum rank or perceived status at RealGM. Flaming, trolling or abusing users in any way will not be tolerated and will lead to a warning.
1c. Members who disrupt the normal flow of dialogue or otherwise act in a manner that negatively affects other users’ ability to engage in real-time exchanges may be warned.
1g. Members should remember this forum is aimed at a general audience. Posting pornographic or generally offensive text, images, links, etc. will not be tolerated and will lead to a warning. Members who repeatedly evade the language censor to post offensive language may also be warned.
As such, if you run into ANY instance of homophobic or racial slurs, please use the "Report" button on the specific post. This is the quickest way to alert a mod to a violation. In fact I know a lot of your posts are on the GB, the "crackdown" policy there IS zero tolerance for any of that.
Cheers
