I can understand the desire for validation and support from friends, but you realize the nature of politics is that it cuts both ways, right?
It's not all black and white.
There's things that you might cheer for that might give me that "fear of being lightning bolted if my life is out of control amidst current events that actually exist", as you put it. Likewise, I'm sure there are things I might cheer for, that will equally give you the same feeling.
Validation and support are something everyone wants, but I hope you understand, politics does not only give you validation and support. Sometimes it gives rejection, and the feeling of being alone in the world.
People very often ascribe morality of people based on presumptions of their political stances. Getting labeled "evil" by your friends certainly doesn't feel very good. Especially when talking about politics rarely results in empathetic understanding between parties, or for that matter even understanding of the actual positions. More likely to get hidden, but that just makes it worse really, because then the thinking is just what they'd think of the "real" you.
I'm not really against names per say, but personally I think it does more harm than good. I am definitely alright with politics being segregated if not outright forbidden, though, as I don't think I've seen it ever benefit any community to have it be a regular occurrence.
