I don't think this guy represents any group of people either.
I was commenting on why the woman might be justified in worrying about a physical attack if she embarrassed the creep because he obviously doesn't have much in the way of boundaries.
Nevertheless, "she could have said something" is of course not an excuse for rude behavior. I wouldn't want to excuse his behavior. As I said, if I knew him, I probably wouldn't like him much and certainly wouldn't encourage him to attend further meetups.
Then we'll see how you feel about the situation.
Could you even imagine such a thing?
