Just to let you guys know, this is actually becoming a thing in Corporate America and its not a fad that's going away. Yes it's beyond silly.
I combed through the last 20 e-mail contacts at work, and 6 of them listed pronouns. A year ago it was like ~2. Two years ago it was zero.
HR today pushed an e-mail encouraging people to do it, so I suspect that number is going to increase.
Right now it still feels optional, but I bet in a year or so it will be compelled. "Why don't you have your pronouns, you aren't a Nazi are you?"
Etc. etc. fml.
