I would say no, but that it is involved…
Satire points out how ridiculous the non-satire news is, and hopefully jolts people out of their usual mental perspectives. That’s how it’s always been…
The difference in recent years and decades is that, particularly in the USA, the non-satire news and the actual subjects of it, have been less and less worthy of any sort of consideration other than satire. To the point that we have had many preposterous elected officials who should by all rights never have been given any consideration as potential candidates, nor should they be allowed to continue in office.
Now, satire may give rise to cynicism, which may in part lead to cynical voting, and contribute to the amazing behavior of our political parties in offering and supporting clown figurehead candidates.
As for media and journalists, I suppose perhaps satire has normalized some outrageous stories, and certainly it’s become harder to tell the difference when there is so much actual flying BS. Certainly we have a situation where almost all the mainstream news is now corporate owner and intentionally biased in one way or another, so some people turn to both alternative news and satire, and there are also wacky or just flawed alternative news sources, and people sharing headlines to their friends without even reading the articles, and click-bait sites… so there’s lots and lots of noise… and the POTUS parrots a fair amount of it… and it’s overwhelming how much noise and info there is, and many people give little serious attention to it… so there’s a blizzard of noise.
So again, I’d say news satire is involved in the blizzard, but I would not say it is responsible for it. Often satirical news seems to ring far closer to the truth than non-satirical corporate news, especially in the last 20 years or so.
