I also applaud anyone who takes a moral stand about what they are willing to do, especially if it might cost them something they hold dear.
If that moral stand involves enforcing a standard of conduct on others, then it's anywhere from slightly to extremely more complicated. Enforcing behavior on others for the perceived benefit of all has been responsible for some major problems in the past (for example, not allowing people to express their sexuality), so let's be careful how much we throw in with those pushing to instill a level of behavior on those who want a place of their own to speak freely (to take as an example another part of the comments here, where Ellen Pao calls out Ohanian re: the_donald).
Many of us may support it in this case because it aligns with our values of inclusion and tolerance towards others (even if it's sort of a catch-22), but it's not like leaders of moral charges haven't been known to go too far before, nor like movements haven't been co-opted by other interests before.
Edit: Clarified where the example I was referring to came from, since that might have been confusing in isolation.
