Then you're one of my tribe - which I define as people who speak up even though there's a cost. IMO a low entry barrier, but strangely not much company here.
Well, on the bright side, at least you know why they treat you like they do. I've concluded that I'm on some list, and the government actually tried to kill me and then realized they made a mistake and paid all of my resultant medical costs, then and supposedly forever, but it appears I'm still on the list, because there's always some point in the hiring process where the prospective employer switches from enthusiastic to unwilling to even look at me, much less tell me details like 'why.' Funnily enough, all of my current non-mainstream opinions developed in response to this... They made me.
I also have high blood pressure now. Eat potassium rich foods, get sunlight on your skin, and walk a lot - those are the fixes that I know for sure work.
