I'm 51 years old and have no tolerance for it. I'm not a suck up. I'm honest and wear my heart on my sleeve. However, I will not tolerate being treated like crap. My situation is opposite of what you dealt with, but still feel like I've been pushed out because of terrible supervisor/management. The turnover is terrible for how they treat people. However, nothing ever seems to change. It sucks to have to change your life because of other peoples bs. So I feel for you and completely understand! With all the movements going on these days, I say we start one on bullying in the workplace!!
