Everyone says sexist things. Everyone says homophobic, transphobic, cissexist, heteronormitive, just plain ridiculous things. It happens. What we need to do when it happens is recognize we were wrong, sincerely apologize, and attempt not to do it again. If we see or hear others do it, we need to call them out on it. We also need to let them know that their words can be very harmful and we need to be careful of what we say. That’s just my two cents.
