> I don't get the feeling people discussing politics are trying to solve any problems
It depends on what you view a "discussing politics". To borrow a quote, "politics is the art of the possible." You have to use politics to define what problems are even considered, much less the possible ways they might get solved.
For instance, unlimited spending on political campaigns is either a problem, or not a problem, depending on your politics, never mind if it should be solved via amendment, court packing, or congressional act[1].
I agree, many people go hardcore on tribalism. I would likely agree it is a bad thing that many Americans define politics as, "us" and, "them". If you want to be results oriented, you have to convince people it's a problem, you're going to need to use politics to do so.
