After reflection some years later, I would say I was overly reacted / was overly emotional over it. But it's hard to feel that way at the time.
Alternately, after several more jobs and life experience, I have made the most money by jumping companies and not sitting still. I have also learned some bosses are just dicks / incompetent. That boss was niether, but some definitely are.
So, I don't know where you and your bosses fall. If you genuinely think they would fire you (have they fired others?), then it would be prudent to interview other places. If it just 'feels bad man's, try and take the hazing with some pride that you survived. Over time, they may just respect that you are tough.
Good luck!
