I too am old enough to remember Bush, and honestly... I think this person is seriously underestimating how much more dangerous the Republicans have gotten in the intervening time.
Bush had nothing remotely close to the project 2025 agenda, and Bush didn't have a supreme court willing to tell him that he was literally above the law.
Bush was terrible, no doubt about it, and the people who've been trying to rehabilitate him can fuck off forever. But Trump, and the version of the Republican party behind him, are so much worse.
Bush was also before the Tea Party split. Those are the crazies that left the Republicans and came up with people like Ted Cruz. Then they rejoined the Republican party and threw them much further right, as we've seen with the Maga movement.
You are correct. Honestly fuck every person who downplays trump. People downplayed him into the Whitehouse twice now and everything you pointed out proves them wrong as fuck.
