What if someone wanted a forum for say, Huntington's disease (just to pick a random genetic problem). What if they wanted a section where only people who truly have Huntington's can share their experiences without getting trolled by just any person? (duh, people with Huntington's could troll too, but you get what I mean).
Just to say, not everything having to do with someone's genetic code is "racist". Almost makes me think the OP is just trolling too.
