You mentioned 3 of BLM's positions, or at least your understanding of them, and I told you that I don't support them. Further, the person against whom the President is running also doesn't support them from the little I have read.
Your central problem is this broken into 3 parts: (1) you think most people consume as much media as you; (2) you think the media people consume is as partisan as the media you consume; and (3) you think anyone to the left of you consumes media as far left as your media is far right. Each point is objectively incorrect, but the 3rd point is the worst.
Most of the country is pretty middle-of-the-road. You think most of it exists on the edges, as do people like Tampa, Baron (I like to think he was more normal at one point) and the similar whackos on the left that post on this board.
