I don't people interact politically in real life at all.
Hear me out.
How many of your friends are Republican supporters?
I ask because it's pretty much a given that people don't talk politics at work, along with religion, people are far more reserved around family, and in school there are groups that cater to your political beliefs and one rarely interacts with the other groups in a positive manner.
I say this because I have 3 friends, college age republicans(met playing EASHL, I'm their goalie.)
We are all comfortable enough to talk about our political leanings, me a Canadian liberal, them American republicans.
These aren't hillbilly rednecks in some backwater town, these are more the CEO types you see, big money Republican types(although poor as **** now they are in school to become doctors and surgeons).
In the backs and forth, civil discussions I've had with them, I've learned more about American republicans and them liberals than before.
Why? Because we are able to have calm, rational discussions, we respect each other's opinion, I'm not looking to change then for the Republican leanings, they aren't trying to change me from my liberal ones. We are simply trying to understand where I'm coming from, my worldview, how I see things and vice versa.
But how does one replicate that on a large scale?
Now whenever someone meets someone of a different political leaning, usually online, it's not about consensus building, learning about the other side, it's about reinforcing your own beliefs or beating down other ones.
And in polite society in person it's looked down upon to discuss politics.
