Why are Democrats in these deep red states so extreme? In 2014 audio from Kansas Democrats insulting some towns in their own state surfaced. I'm in DC, a 4% Trump city and you don't hear people talking like that. You'd think Nebraska Democrats would be blue dog salt of the earth types.
Lack of power breeds frustration.
1) RE: the OP, absolutely disgusting, and I'm glad he was fired. There is no room for a major political party to tolerate views or statements like that.

If you're a Republican in Western Oregon, and you very much feel like your "version" of life in Oregon is a conservative one, you will eventually start to *hate* the folks who outvote you time after time after time and keep your state non-Atlas blue. Same with Democrats in Nebraska. Conservative governance is unavoidable for them, and it'll breed contempt really quickly.
That's kind of a national thing right now. We don't have enough votes and there's not much of a center.
