I use both CC and LC, but they don't require anyone to be nice. Hell, being nice to trooms get you called a handmaiden or the other names. Half of the MtF thread on LC is, "I hope this faggot joins the 41%." and on CC it's more theoretical and less aggressive, which is all fine and good until they go apeshit and their opinions leak into non-related threads.
Still, segregated women's forums will always be raided by men with child porn and gore and not vice-versa, which really speaks to how women aren't allowed to have their own space, but that's a conversation for another day.
