I submit that Conservatism is a mental disorder. Prove me wrong.
I'm pretty sure it's genetic due to the apparent 50/50 split in the population.
To a liberal, it certainly looks like a mental illness, but be aware that from the conservative standpoint it is the liberals who are mentally unbalanced or BSC.
Remember the half-black half-white episode of Star Trek? It's like that but the difference between the two is invisible and doesn't present itself until ideology surfaces during conversations.
You know when it happens because you can feel the small hairs down your spine rising...
Along with your blood pressure.
You've had a close encounter with someone who is batshit crazy.
