I may be the odd one here but my career consisted of finance and software engineering. Until my current job, there was always screaming and yelling at all my previous positions that I just assumed that was the norm. It’s more likely that I’m just extraordinarily unlucky because as you’ve noted, not screaming or belittling colleagues is the norm in much of society. I think my issue was that I’ve experienced it so much that I just accepted, especially since I saw it happen at my very first job.
