So? Flag their messages too. You and I are both agreeing what Trump is saying is horrendous.
And, for what it's worth, I'm gay and a part of a minority and I am privileged to live somewhere where there's little repression for who I am.

I'd take "virtue signalling" any day over whatever this response from Facebook is.
