Ok fair enough. Where I’m from, that is not the case.

I dont know. People maybe dont like showing support for minorities.

Required or pressured? Is that the same as encouraged in your world?

What we do in our office, to make sure everybody feels supported, is to have rainbow decorations, and badges and stuff for people to wear.
You could wear a rainbow badge, to show that you support, and so he knows to feel safe. You can also encourage others to wear a rainbow badge, or lanyard or something else, to show that he can feel safe.
