That's the key. When you find yourself saying "how can people be this evil, have such silly ideas" ... the ideas the left spouts are always fake and a front for money/power//power/money. They don't believe in them.
Sometimes I have to remind myself that the leadership doesn't believe a word they say, or care about a thing for which they claim to fight.
After that self-reminder, there's no longer a need to try to understand how they can come up with such ridiculous politics and ideas.
The money wags the ideas.
Political ideology is what each party disbelieves but trots out to win our votes, after which they continue to steal as much of our money and gain as much power as they can.
