Yeah, understanding the other side is difficult.
I'll try to explain the other side, but it probably won't make sense to you. (as your side makes no sense to me) The trouble is that people can have fundamentally different value systems, priorities, and fears.
Maybe the best way to explain it is to say how you appear to the other side. I'm sure you will disagree, which is kind of the point.
You look kind of naïve and childish. You appear to believe in some utopian fantasy where all people are good and have or can be converted to a value system that is like your own, with the possible exception of conservatives. You fail to make any effort to protect your nation and culture from being overrun by the brutish, violent, and lazy. You somehow imagine that people from places like Syria and Mexico make better neighbors than many of the conservative people in your own country. Basically, your views fail at self-preservation. You are in denial of the historic fact that every nation is built upon a hill of skulls, and the fact that this is the natural way of nature. You imagine that you can refuse to pile up skulls without becoming part of the pile.
If your world were real, I'd rather live in it. I'm not going to deny reality just because I don't like it. Conflict is eternal. I prefer that my people win.
It's actually unethical to avoid the conflict. You're ceding ground to the enemy. You let down your descendants, friends, and neighbors. They will be impovershed, killed, and -- as we've seen with ISIS -- enslaved. This shit really happens. It may take decades or even centuries, but every bit of inaction and appeasement brings that day closer.
For some reason, you push risk and long-term bad consequences out of your mind. It's like you can't see them. You focus on the positive only, kind of like a gambler.
Your optimism probably makes you a happier person. :-)
