Reminds me of me trying to explain to a friend:
Me: "Left and Right wing politics is just a spectrum of how much you trust your government. Extreme Right, you are basically an anarchist. You want as little power to the government as possible. Extreme Left, you want total power to the government. You have to expect that voters still wants what is best for their country and the world, that's what you have to expect. You can't expect people to be evil, just because they are Left or Right winged."
My friend just replied: "That's not true. Companies and capitalism is evil."
