Unfortunately I've met a few.
I was a search and rescue mountaineer/EMT for a decade. There are bigots in the field. You get a lot of "conservatives" with military or law endorsement backgrounds.
Also, to take something like this down, you'd start from the top and rappel down to it. It's how they do most rescues on El Cap (or any cliff for that matter)
They point at imagined or minor hypocrisies on the left to make themselves feel like their own is ok or that everyone is a hypocrite
