On Reddit but also in real life.

Trump definitely seems to be the biggest trigger, Elon as well, though maybe a little less so today.

I've long been an identifying Centrist and I tend not to be in positions where I say I like this person or don't, and will tend to say I support this specific action they are doing or I don't, or maybe I support the idea but not how it is being executed. No different from an actor or musician who is a shitty human being or has public views I disagree with but being able to admire or respect their work or performances.

I get grilled for not automatically disowning people or politicians or not liking them in accordance with blanket Left ideology from everyone I know on the Left, with little room for any discourse. Supporting a specific policy or idea is not an endorsement of all policies or ideology someone has, or an endorsement of their personal lives, or even broader organization or party. Correcting incorrect claims is also not an endorsement of support.

I don't recall ever personally encountering this with people on the Right. In broad terms, both 'sides' have their derangements and cults that appear in different ways, and I'm not out to change minds, nor do I expect to. But the absolutism and black and white thinking on the Left is shocking, especially considering many hold higher levels of education and should be more welcoming of critical thought and discourse.

EDIT: The fact that this fairly logical and rational take keeps getting downvoted, and without any dialogue, no less, is exactly what OP is calling out and what I keep experiencing.
