Humour is often used to find a common ground. Humans are very uncomfortable if they don't know what another person finds appropriate or not. Faking it isn't the best way to respond to that because it gives the other person false data. I'm not going to defend the "bruises" guy because I have no idea what the context was (though I doubt the context makes it any better), but if you desperately try to fit in, that's a problem.

Of course there's no point in blaming the victim. Most teams don't have an inherently inclusive culture. Maintaining your differences when you join an otherwise homogeneous group is hard and most of us (probably women even more so than men, because culture and testosterone) were raised in a way that makes us think trying to give up our identity in order to fit in is the right thing to do because it reduces the potential for conflicts.

Ideally teams should be inclusive. That is difficult, because it goes against much of human nature (othering and tribalism used to be a good evolutionary strategy). Sometimes getting it right can be impossible. But it's worth trying.

There's two sides to this issue and both are difficult to fix. But we need to understand that they both contribute to the problem. This problem is deeply ingrained in our culture and in our natural psyche. It won't go away just because we tell people to stop doing it.
