Honestly, slurs are almost solely used here as an ad Hominem. That would be aort of cool. There is literally no point for slurs, but I wouldn't want to ban that. Instead I would want someone to check people who continually bring down the pyrmaid of debate to ad hominem level. If they reach a certain kara threashold and nearly all of there posts are fallacies from their user creation until that point. Ban them.
