Maybe I wasn't clear enough with my criticism: You are unambiguously making a value judgement that the feelings of people who get offended by comments like "Y'all colonized the poorest parts of the city and gave the poorest folks nowhere to go" are more important than the homeless who are being baselessly accused of being murderers. I don't think you honestly expect me to believe this discrepancy is simply because you "see a more-or-less random sample of the comments", but if that is the case, simply search for "homeless" in the relevant discussions and have at it -- if you still can't see the problem, then read the results again replacing "homeless" with "y'all" or "people like you" and see if you feel the same way about whether they could use commenting on. The only way you can possibly justify the way the guidelines has been handled is if it operates on the idea that people who are less represented here, such as the homeless, don't deserve the same courtesy.
