"You guys" is harmless. Watch a US Open tennis match. When it's over, the winner gets interviewed and always thanks "you guys," meaning the fans in attendance. I wonder who among them is offended.

The "pronoun" thing is not about people referring to themselves. People referring to themselves use first-person pronouns, which are non-gendered and non-controversial. And when you refer to someone with whom you are conversing, you use second person pronouns, also non-gendered. So the whole point of the "pronoun" announcement is to tell you how to refer to the claimant when he, she, them, or it isn't even f*cking there. It's a test, not a practical request, a shibboleth for wokeAF people to show off their commitment. It has nothing to do with actual communication.

I don't believe that using the "wrong" pronoun, except pointedly, really offends anyone. It just gives some people an excuse to offend you.
