Trump has destroyed huge swaths of the American federal government. Wiped environment regulations off the books. Installed hundreds of conservative judges that are poised to strike down all sorts of legislation that codified citizen's rights. Covid-19 is not a hoax. A quarter million Americans have already died from it. Ten million have been infected. And he's doing everything he can to take away their healthcare in the middle of global pandemic. That's a tiny list of the actual destruction he's already pulled off.
None of the above is "in anyone's head". Now sure, if you are of the ilk that doesn't believe in climate change and also is one of those who believe the private sector will save us all, you may like what he's done. To those of us who listen to scientists, he's a clear and present danger to the whole world.
I agree that not talking to each other is a path to failure. But you can't talk to people who won't even entertain a conversation. And the typical Trump voter will tell you to your face that everything you hear or read that hasn't come out of Fox News or Trump's mouth is a lie. Regardless of how much evidence you provide to the contrary. You can't have a productive conversation with people who believe bald faced lies.
