There is nothing like the joy of punishing those that don't support your political beliefs. The smug superiority that comes from knowing how much better we are than those other stupid people.
Hurting them is actually doing them a favor. If we hurt them enough they'll eventually understand that doing what their betters tell them is the proper way to live.
Again, if you find people who act contemptuously to be contemptuous for that contempt, you are doing the same thing.
They are saying people who vote to harm themselves are contemptuous in part because self harm is evil and should not happen and in part because voting to harm yourself, whether a person knows it or not, may also be evil because it harms more than just oneself.
So we see that liberals who believe that conservatives by voting for self harm are immoral, whether they know it or not. This to them is justified contempt. They hate such evil.
Conservatives, on the other hand, as you expressed here, feel that such hateful contempt toward conservative is itself the real issue. Anybody who is contemptuously hateful and willing to dump that on them is the evil infecting the country.
So we have the contemptuous of self harmers on the one hand, and the contemptuous of contempt filled people on the other duking it out.
For me, however, what I see as the relevant issue is whether what one votes for is better or worse for society generally.
Where should the focus be? It should be on whether we are voting for making life better or worse, no? I can do nothing about liberal contempt for conservatives or conservative contempt for liberals than to say that in my opinion they are full of contempt. The moment I find either or both contemptible I join them.
Let he who is without sin cast the first stone. Good luck with that. But to harbor contempt, if one is aware of the evil nature of hatred, will make you contemptible in your own eyes, and that’s the real problem to me. We cane to the table already feeling contempt for ourselves. If we could deal with that all this absurdity would cease to exist.
