Instead I said nothing and hoped nobody forced the issue by asking me to join the discussion. These things are immensely uncomfortable for a portion of the population and businesses know that, they just don't care. In fact, they keep making them worse and worse.

Feel bad for ya. I’ve been retired since 2011 and I still remember the useless yearly diversity crap we were required to attend. Probably went on for 10 or 11 of the last years before I bailed out. As usual there were a couple of folks who found it beneficial(?) but the majority, not so much. Must be worse now. Always had to be careful about comments made that could be overheard. Even if they were meaningless to you and who you were conversing with.
I went through that at a university before I retired.

I never got a privilege that would make it up to me for what I (and you) go through.
