To each his own. I do politics sparingly. What I see when I go to read comments on the politics are always, "Oh yeah! Well what about the left who did this?" or < "What about when the right did that?" As if someone even daring to crack a joke that has nothing to even do with politics means somehow that they are praising or approving of what this side or that side did. That is irritating. It's the default reaction to anything on the political spectrum.
I think some folks are tired of reading it. Because that is the only way to know it's politics. Then they have wasted their time. That is what I have seen mentioned quite a bit.
