eh, I'm not going to cast stones at people who will voice support for the right to reprehensible speech and will fight for a system that makes sure even people with reprehensible speech have recognized rights and can get legal representation, even while they personally do not want to represent nazis etc. That's not a moral failing.

Suggesting a group is in some way a failure now because they don't use their speech how you think they should is, of course, at least a bit iffy while we're talking about this :) but FIRE is probably the group you're looking for today.
