Satire And Americans

Do Americans not understand satire? I'm not trying to be mean here I'm serious...
It seems every time someone posts a story which is clearly satire (like Joe Biden stepping out of the race to lend support to Biden) their immediate reaction is "this is fake news" (which by the way I find more ignorant a response than comparing coronavirus to diabetes or suicide rates). Of course its fake, usually that's what satire is. For the undereducated, this is a SATIRE website https://www.theonion.com
It seems that Americans can't seem to grasp the concept of satire. This goes back a long way in observations and includes friendly bantering with sarcasm.
I remember as a teenager my friends and I were cutting each other up with sarcasm and their American cousin just sat there mouth open stunned that we were so insulting toward each other. It must be a regional thing I'm sure but I find very few Americans seem to get satire and sarcasm (both meant in a positive way not actually demeaning).
Like I said, I'm not trying to be mean or rude, it just seems like Canadians use satire and sarcasm far more often than many Americans and I wonder why. With all the "free speech" in the US you'd think they'd take the opportunity often to cut each other up. Perhaps that's the problem though, when they do everyone takes things down there so damned seriously that you'd have to worry about being sued constantly. Ironic how they give everyone free speech and then others the ability to profit off of it (this is sarcasm, obviously lawsuits are based on slanderous comments, however, it just goes to show sometimes how "not free" their "free speech" really is).

The meme below is an example of satire, which is backed up by the article link as being "not true". An example of satire. Corona beer sales are fine, this is just jokingly linking the beer name and deadly virus and pointing out the prevalent IQ of people who actually think beer sales have declined or the few who think coronavirus is linked to the beer itself. It's called satire. It's called humour. https://www.nytimes.com/reuters/2020/03/03/business/28reuters-china-health-constellation.html
