When I was a kid, my family watched the news every night. We had 30 minutes of “World News”, at the end of that broadcast there might be a “commentary” segment. It was clearly established this was commentary. People selected which network to watch based on the commentary that best aligned with their world view, but, they did not have this virulent hate for the other commentators that we see today.
Now, everything is commentary. There is no line, we hate everyone who does not speak to our personal bias.
