Not sure it's about defending Trump voters rather than the limited utility of calling them stupid. Cards on table, I flit between here and Facebook some nights and on there, do trall the news feed and call perfect strangers morons and the like. Because I find it mildly cathartic and it's that type of arena. There's no real discussion. Not big and not clever, but some times you just want to chuck a brick.
I've got no time for the patronising, let's hold hands and try to understand the misguided masses thing. I don't think anyone's doing that here but there was a element of that during the Brexit aftermarth in the wider world, media. A lot of the Trump voters, as with Brexit, are far more better off than I economically, social Capital wise anyway.
Here, when it's good, is somewhere to look at the motivations, drivers, context of why people are drawn to political tendancies. How societal, economic forces are playing out and being exploited or potential fruitful lines of defence / argument. My only objection to the volume of look at these stupids, Trump is a rotter, type posts are it's just a bit tedious and doesn't leave us learning much. Some might see that as wanky debate club stuff. I see it as useful to at least martial your own thoughts and come to an understanding where you are philosophically speaking.
