I will also note that not only have I never seen a mountain biker with a MAGA helmet, I have yet to encounter a MAGA anything in the woods. My "sense" is that they tend not to be in that crowd, which is odd, because you couldn't get a whiter sport. Not even NASCAR.
Ever notice that the only black guys you ever see on bicycles are homeless? That's it. Did I just ruin my attempt to hide my white supremacy?
