Yes, we clearly just have a fundamental disagreement (which is fine). For example, you think "People are Trump supporters because they believe the basic tenets of the positions are valid." I think people are Trump supporters irrespective of the basic tenets of the positions because they've been captured by a cult of personality. I've seen, on countless issues, Trump supporters accept a 180 degree reversal from what they purported to care about under Obama.
I also completely disagree with your take on the ACA, which I view as a false Republican narrative. It's not worth rehashing in depth, but in my view the ACA was fucked up precisely because the Dems bent over backwards to try to accommodate Republicans in the foolish hope that it could be bipartisan. It was a Republican plan to start with, Republicans had significant involvement in its early development, there were dozens of bipartisan hearings, and a number of Republican amendments were passed. Yeah, after Dems finally realized that no R would vote for it out of pure, cynical, partisan calculation, the Dems passed it on their own, and then the Rs used that against them too. And cowardly Dems ran away from it for years, until some young Dems with guts finally stood up for it in 2018 and a blue wave crashed over the House.
And you mention the GOP tax bill. For all we hear about the mean Dems ramming through Obamacare, where is all of the fallout from the GOP ramming that turd through with zero hearings, zero discussions with Dems, and the text secret until hours before the vote? Yeah, it's proven unpopular, but the process is a non-issue.
The point being that it is the substance that really matters, not the process. Dems lost the ACA argument for years because they were too scared to defend it on substance, until they finally did and took the House. Republicans have so far lost the tax bill argument because it sucks, but their process in enacting it has had no impact. If the Dems ram through a bunch of legislation, they'll stand or fall on the quality of that legislation, not whether they wooed some Rs to vote for it. And if they have to water down the bill to get those Rs, like with the ACA, it's more likely to backfire than help.
