It seems to me you have (and are currently) experiencing a lot of rejection: shunning, blacklisting, obloquy*, pattern rejection*, and avoidance campaigns. You may also be experiencing paranoia to boot.
Now I haven't experienced much of this. The only things along these lines I can recall I expect I fully deserved. For instance, the time I spilt coffee at my wife's mother's** house, I got the full dose: shunning, blacklisting, obloquy, pattern rejection, and avoidance campaigns. From both my wife and her mother. It went on for days. I amply deserved it. It was, after all, the Royal Doulton with the hand-painted periwinkles.
But I don't remember ever experiencing them on a continuous or wide-spread basis. I suspect anyone who does is either a fully reprehensible person or paranoid. People usually don't shun, blacklist, obloquize, pattern reject, or avoidance campaign someone without good reason. I mean, shunned? Actually? It takes a lot to be shunned. Like the Royal Doulton with the hand-painted periwinkles.
Now sure, some forms of rejection are unreasonable. I just read that Wagner was so anti-semitic that he wore gloves whenever he conducted Mendelssohn and left them on the floor afterwards for the cleaners to pick up. But recipients of discrimination are quite aware of the cause for this and don't feel rejected wholesalely (if that's a word? it should be). I mean Jews may feel discriminated against by Christians and Arabs; blacks by whites; gays by straights. But even members of these groups don't feel everyone hates them.
But I'd be interested in listening to those who have experienced shunning, blacklisting, obloquy, pattern rejection, and avoidance campaigns. Especially the obloquy and pattern recognition victims.
* And a large vocabulary. Obloquy? Pattern recognition? The first is defined as (1) strong public criticism or verbal abuse or (2) disgrace, especially that brought about by public abuse. Now that I can understand. I once experienced it when I farted in church. I could find no definition for pattern recognition on the internet, although I did find a long paper about it from the Computer Department of Columbia University. I didn't fully understand it but it appeared to be about algorithms to recognize associated groupings of data. This may upset numbers and such, but I don't think that's what's pissing you off. However, I do recognize a pattern in your complaints.
** Mother-in-law is English by birth. Like the Queen, she always wears gloves and a hat and carries a purse. She also wears jackboots to bed. She detests me and displays the full panoply of shunning, blacklisting, obloquy, pattern rejection, and avoidance campaigns towards me. She has many additional ways of making me feel not wanted.
