That's an interesting proposition. I wouldn't go so far as to say extreme perversion is a mark of a liberal, although we see plenty of examples of that. I don't know many transexuals who are conservatives. Have you seen the 1993 Michael Douglas movie "Falling Down"? It shows what can happen to an otherwise normal man when all those things that matter to him in life are taken away, one by one. Job, wife, dignity, credit, kids etc. Person under stress snaps. Takes it out on those around him. Yet he sees himself as the victim, as he harasses others. (Good movie.)
What I'm saying, is that some people who might consider themselves conservative may be under stress and have snapped, and harass others yet do not see themselves as an instigator and troublemaker. It's one facet of human fragility, getting stressed out and then partaking in perversions. As you say, once in a while they reveal their true nature. Yet they don't see anything wrong with the perversion they display, continuing to think they are conservative, and that is troubling.
Liberals ARE under extreme stress, so they fit your example. Liberals have rejected common sense and personal responsibility. They have accepted group control of their lives and undermined their own personal integrity. They are always frightened because they can never trust their own feelings or opinions without first getting group approval. They hurt others and do evil at the command of their groups, while knowing they do wrong. They live in sheer hypocrisy. And, I believe, it drives them insane with stress and fear. It’s why they ALL take antidepressants, to stop themselves from feeling anything at all, so they don’t have to experience how wrongly they are living their lives.
