Nothing they said was sexual. Even if they were saying they are attracted to men (as a man), that is not sexual.

By your logic, no one at work can say they are married (married people are attracted to each other and have sex, how disgusting to force us to talk about your wife at work.)

And don’t you DARE say you went on a date recently (dates are romantic, and that is sexual. Stop forcing your straightness on us!)

Also, the trans flag was included, so they weren’t even talking about sexuality, just gender.
