There is no point ever debating Trump. He has developed the Gish Gallop to a whole new level that even Duane Gish would not have believed possible to get away with. He will just keep spewing bullshit so fast that you can't even challenge him on one thing before he has moved on to claim something even more outrageous. Trump has no shame, there is no claim so infuriatingly blaringly false that he won't boldly claim it as true.
Trump will stand on the stage and with a straight face claim that after when George Washington crossed the Potomac to defeat the French in the Battle of the Bulge, he then gathered all the founding fathers at the Last Supper and they unanimously agreed that America would be a heterosexual Christian nation for only Americans forever, and he is here to make sure that remains true! Then while Mayor Pete is about 4 words into trying to explain just how stupid that is Trump is shouting over him abiyt how that is proof that 'The Gays' cause COVID.
There has been a lot of effort over the years on how to counter the Gish Gallop, and the best way it to pre-emptively refute their main point, but you can't do that when the Galloper will just make up things on the spot. There is no known technique for winning against that. In the end the reasonable one ends up looking incompetent for not being able to get even one good point in against the firehose of bullshit. In the end no one talks about your well reasoned argument on why the National Debt is not really a problem, all they talk about is how Trump doesn't know even the basics of history, and while you may think that is a negative for Trump, it is not. They are talking about him. His name is in the air, and yours is not. Besides that, most people don't really know when or why Washington crossed the Potomac or what battle he fought there.
The only way to win against weaponized stupid is to not engage with it.
