There might be very little alignment of political opinions within one's circle of friends, and any discussion would turn into an unpleasant discussion with the risk of ending the group of friends forever.

For most people, very few friendships form with an expectation of political agreement: activists met at a common protest or campaign, generic regulars of a popular political party or union, old style secret societies, and so on.

I think people can aim to meet politically aligned people at non-political events/places. I met most of my friends in venues that "members of the opposite tribe" just don't frequent. And I feel like it goes for both sides.

Yeah. There are exceptions. People can also have multiple circles. And it's not as if political opinions within a group are really uniform. But there does tend to be a certain degree of uniformity within many groups of friends.
