It's interesting to me that I came to this forum (invited by a friend) because another forum we participate in had become too homogenous. I now realized that that homogeneity developed from being rational. It is very difficult (even in the Loft) to maintain a genuine, thoughtful, rational discussion for even a page before being infested by trolls and partisans. It doesn't seem to matter the topic.
I've been a moderate/independent most of my life. I've campaigned and voted for both Republican and Democratic candidates over the years. I used to ignore party affiliation and voted for the candidate that best mirrored my views. I still do that but party affiliation matters to me a lot, now. I got burned by HW Bush - I had believed he was a rational actor, but he became a party stooge. The environment changed substantially after Ford, and irreparably after Reagan/Gingrich. The GOP of my formative years doesn't exist any more (I think Nixon killed it).
But the level of acrimony, inanity and downright nastiness is just overwhelming. My "ignore" list is practically a page now. I can go to a thread and find an entire page is nearly blank, yet that doesn't prevent the spread of the infection. The fringe absorbs the garment. I don't know how to fight it. In my view, "the middle" is where it happens - where the rubber meets the road, as they say. Lately it's just hard to find the road, which, I suppose, is where we operate on common facts and understanding. Our information silos and bubbles prevent us from talking.
