It might be taboo to say it, but I was about to mention this. I worked in all kinds of job, and from my experience, jobs that are blue collar or high school educated tend to have these kind of shit stirrers. It is like they are still in school and never grew up. But affluent professions are not immune to having assholes either. The more affluent folks are not into bullying and shaming people, but many of them are snob.
