I agree with those who say that discussing politics may be a useful part of an exjw forum, because it's another aspect of breaking free from the 'neutral' (haha yeah right) cult.
The problem though is that politics is a very location-bound topic.
Most countries do not have Trump as president.
So for many here the pro/anti Trump stuff isn't too interesting anyway.
Most countries also don't have two-party system that seems to have evolved in a toxic situation in which nobody seems able to cooperate and many people don't even sincerely try to understand the other's point of view. (Some comments in this thread are sad examples of that).
Sure, it takes practice. But with so many politicians and media showing exactly how civil discussion should not be done, I'm afraid it may be hard for people in general (and that includes us) to have civilized, meaningful conversations on (USA) politics.
