While I agree that his utter failure as a president and his sadistic policies are crucial...

His job performance and policies and his body count are as much of an issue to the people you mentioned above as his taxes. In short, not at all.

You think these same people you're discussing wouldn't either tacitly/actively participate in the extermination of people they feel are undesirable?

Your argument is nothing matters except for stuff that actually matters. I agree with you that with portion of the population ~30-40% percent NOTHING matters. 30% of the population is predisposed to authoritarianism which is why his ceiling is what it is and his floor is what it is.

Of that 50% number (we're going ahead and using for east) there's a significant chunk of people who want to cheat on their taxes but don't wan't other people to. Those people matter.

The point isn't to get flip people we can't. It's to get people who didn't participate last time. And if they sat out last time they weren't really paying attention and were swayed by both-sides-ism etc.

Also, if you want to talk policies a tax cheat who's only achievement was signing his enabler's tax cuts for the rich isn't a good look. Neither is the fact that person is doing everything in his power to eliminate healthcare.

It's not old old news. The tax returns are new news. They provide confirmation and they provide a way to begin a reckoning. They didn't fight tooth-and-nail (in and out of court) to hide them because they don't matter. Also, in a week that saw their Trumped up Biden Republican-led investigations fall apart actual, digestible evidence of his own criminal behavior couldn't be better timed.

If we pre-emptively say "these things don't matter" then they won't. We must make them matter. If people can make people believe that Donald Trump was sent by Jesus to stop pedophiles despite being an actual pedophile sent straight from the pits of hell, then we can make sure people whose brains and hearts aren't rotten to the core understand who he is, what he has done and what he will do if he succeeds in stealing this election.

Also, we have someone in this post in the year of our Lord 2020 asking if he's not really a billionaire so it's not like everybody 1. Has been paying attention 2. Is media-literate enough to make sense of the information they might have been paying attention to.
