"It’s not a party, it’s a cult."
The weirdest thing about much of the Trump hatred is how so many of those people actually believe that. They have this mental image that everyone (or at least, almost everyone) who supports Trump is completely blind to his faults, and that's simply ridiculous. Sure, there are some people like that, but the vast majority of Trump supporters I know personally are well aware of his flaws.
They support Trump for a combination of two reasons:
1) He has been very good on a lot of conservative policies, even if not all of them. As Mitch McConnell correctly stated, this has been the most conservative Administration in the last 30 years;
2) the only realistic alternative until 2024 is a lunatic Democrat Party that has moved rapidly to the left in the last decade.
Supporting Trump for those two reasons isn't cult-like; it's a reasoned, logical position.
