I'm not sure I follow how some former friends booting you out of a Discord server relates to the media. Are you giving that as an example of people so immersed in a left-wing media culture that they can't handle differing opinions? That's certainly something I've seen more and more of on both ends of the political spectrum. I do think there are more moderates on the left than the right, but in both cases the extremes do seem to be hostile to nuance.
