Steven, I think part of what some folks here are trying to express is that the way the rules are set up, the onus is on the person to be kind and patient with a bully, instead of on the bully to stop doing their bullying.
Imagine a Wikitreer calling your people and community "inferior" and that they deserved to be genocided. If you get upset, now you're the bad guy for not being silent and accommodating of the racist person who said those things. The racist person doesn't get in trouble. You get in trouble. You get Mentors and other Wikitreers lining up to tell you how bad you are, how you don't contribute to the community, how your feelings are wrong and the only person who's feeling matter, apparently, is the bully. You can say, "oh that would never happen" but myself and several others have explained repeatedly in this thread that it HAS happened. More than once.
I'm not sure I should speak on behalf of Melissa and the others, but I think a statement from the Wikitree Mentors that racism, homophobia, etc., is not acceptable on Wikitree and is not part of Wikitree's culture, would go a long ways to assure people that their concerns are being heard.
