Why do I only see one political party being complained about here?

Why do I always see posts on here about protesting, complaining, or "organizing" against one political party from the people on here? I never see any of these against any other political party. All these people don't think that only one political party can make mistakes or do dumb things, right?

I've never been part of any party, so I don't really understand the tribalism. Are the people who are from Missoula and on this sub so politically captured that they can't help themselves?
