I'm a millennial but this reminds me of when I first got into the work force and was stuck in an office full of boomers with me being the youngest. I remember the boss would take turns taking shots at different people during meetings, making insensitive racial jokes about people. I eventually got tired of doing the uncomfortable fake laugh so I just sat there stone faced during his jokes. He halted the entire meeting to a stop to ask me why I wasn't laughing. This is the extent to which office culture must be obeyed and how insecure they get when you don't go along with it. It's so pathetic.
Ohhh yeah, there was that too, I can definitely recall one of my male managers making comments about a woman's body when she wasn't in the room. So gross.
