Friendly reminder, politics isn't sports. You don't have to choose a team, and if you're part of one party you don't have to call the entire other one stupid. Especially since they likely have good reason to say the same of yours.
If you've ever said "that's not the way it was when I was a kid" you need to ask yourself if 1. You're remembering it wrong or 2. It was that way but your parents/society made it seem like it wasn't.
