The best part about the strict filters is that it creates a barrier to entry to talk about these issues, because you have to know the correct language to discuss them in. It significantly improves the signal/noise ratio, where noise is the typical "I don't understand these ideas therefore they're wrong" and "You will never reach working people if you expect them to learn how to not be racist/ableist/etc!" and my favorite "This one time a 'woke' person on the internet was cringe and/or mean to me so I don't have to listen to you"
