At some point I would think you would run into anti-discrimination laws, but short of that sure do what you want.

I'm free to say to those users "hey, come post here my lgbt brothers/sisters/anything in between. Come post here liberals who are pissed off about the actions of facebook/google".

Whereas if I said something against the government of china they would just toss me in prison or have me killed.
