Only 5.3% of US welders are women. After years as a professor, I became one

Shop talk and banter are fairly universal. Any difference is going to be a target. Thin bloke who doesn't look strong enough? Ginger hair? Tall guy, short guy? Weird tattoo, etc. Definitely the one black guy or the one white guy is going to get shit. But is it malicious? Almost certainly not.

The other thing, which in my experience is relatively common worldwide, is that working class communities are more accepting of male-female dynamics. In academia and in highbrow society the tendency is to basically sanitise every social interaction. When you're in an environment where that isn't happening then you can't suddenly ignore it any more.

IDK, I think it's to enforce pecking orders based on stuff you can't at all help. I grew up working class and hated it--it's essentially bullying, no matter how you look at it.

It's one thing to make lighthearted jokes about some stuff you did, like "remember the time you forgot to base64 decode the images and stored garbage in the DB". It's entirely another to bully people for who and what they are. You're basically daring people to get somehow violent with you to get you to stop, and besides that being dangerous, a lot of people would rather not. It also creates this dynamic where people willing to be violent avoid bullying and rise ok the pecking order, and those who aren't don't.
