Many have. Even people I know in real life have lost it and are calling for purges of anything remotely associated with liberals, even the victims of liberal appropriation. Many of them now hate America and want to return to monarchy and pre-Enlightenment society. For some reason they've decided that too much freedom is the culprit of liberal craziness and "degeneracy", which is the opposite of their original view. And anyone who holds on to their own old values is now a liberal in their eyes. If you want an example, there are plenty on this site alone.

Most of the others withdrew and became apolitical, and more extreme ones turned to different names such as libertarian. They are no longer accepted by their former allies.

The only people I've seen recently who still talk about "conservatism" are liberals who use it as a dirtyword for anything they don't like, and diehard Trump supporters who don't care about anything but Trump and live in the past, oblivious to this recent development. I don't mean people who like Trump, but the ones who worship Trump like he's the messiah and can do no wrong.

There's still a few stragglers like I was for a while, but I noticed my friends and family members starting to say some really concerning things, and it matches the pattern I've seen online.

Conservatives split off into completely different schools and the term no longer has a solid definition. At this point calling yourself conservative basically just means you're not a liberal, which of course isn't saying much. But what I'm amazed with is how suddenly it happened, and what could've triggered it. My main suspicion is that the George Floyd riots painted a new picture in some peoples' minds of liberals as anarchists rather than big government loving totalitarian commies, causing the more reactionary ones to go the opposite direction.
