Also weirdly mountain biking has me fucking confused. So many magats on my trails, and it was my impression that cycling in general wasn’t as popular amongst the “anti-woke” crowd.

(MX Enduro and Mtn biker of many years here and I've observed the same thing)

It has nothing to do with liking/disliking bikes and everything to do with the toxic masculinity culture of "conquering" a hill, or trail, or just in general being more in the "bro" culture that does tend to attract more magats than other hobbies I've picked up.

There's a nontrivial number of mtn bikers that are in the maga crowd, and the only link I can find is that this tends to attract a lot of people similar to the Andrew Tates of the world.
