If one sees themselves as the perpetual victim who is misunderestood by the larger world to the point where they have to retreat into a world of their own construct, where the rules are different, reality is different, and how they percieve both themselves and everyone else is different... then there is very little anyone who does not subscribe to that mentality can do to change it.
The constant refrain becomes a variation of several continual complaints.....
-- you do not listen to me
-- you do not understand my point
-- you do not like me
-- you like so-and-so better
-- you are attacking me
-- you are being mean to me
-- you don't respect me or my opinion
-- you are trying to make me like you
-- you just don't accept me for who I really are
Notice that everything is the other persons fault. Its all the fault of the other person in their attitude, their perception, their motivations, their actions, and their approach. The individual who has this unique mindset of the perpetual victim stnds apart and above it all and has convinced themself that they are blameless, faultless and have done nothing wrong at all. Everyone is indeed out of step but them.
The more this is pointed out to such a perpetual victim, the more resistance grows and becomes like cement. In fact, criticism from others only serves to perpetuate the feeling of victimhood and the desire to retreat deeper into their own world where only they are understood by themself.
Persons who are more vocal in their criticism are singled out for obsessive opposition bordering on the unhealthy. They go on a list of persons to be despised and hated and opposed at all costs no matter how silly such vendettas make them look.
Of course, the worst transgression of them all is to point out the reality of this behavior. That puts you in a whole new category for derision and anger coming your way.
Victimhood is not healthy. Victimhood combined with obsession is even worse.
