In other words, the other side should accept us, regardless of our politics, because that's human thing to do and politics should not interfere with normal human endeavors. But we are OK to exclude the other side because it's beyond politics, those guys are just pure evil.

I hope you are smart enough to recognize it can't work this way. There always have been politics and it was always "fight for America". Even before there was America, actually. If you want to have any civil society, you need to learn to engage with people who disagree with you. If you can't, both sides lose.
