Conservative people tend to protect their believes, no matter how wrong they are based on new evidence. Humanity has many examples of this happening through millennia, it is widely documented...
You can replace the label "Conservative" there with just about any ideology or political leaning.
I think people on the left arguably did the same with various social justice initiatives. Things got crazier by the month for a while until people were genuinely afraid to speak, people were being cancelled for dubious reasons, etc. I recall long periods of needing to be very careful about how (not just what) I said to peers and even some friends. This was a very left-driven phenomenon. While it was started with arguably good intentions, it got weird.
The right has adopted this, ironically, though in a different way and for different reasons. In both cases it's about ideological purity and power, though
A lot of the other stuff, like actual policy, they're still pretty dug into. But IMO there's a greater proportion of that stuff on which they're just correct, so that's kinda respectable for me.
I'm not seeing that; not yet anyway.
I expected to see that after the disastrous election that demonstrated just how fringe some of those vocal views were, but I did not.
Is there much left in there besides extreme hypocrisy and cognitive dissonance? Their beliefs seem to be highly fluid and aligned with whatever the dear leader is saying at any given movement. Daily radical swings are not that uncommon..
