Some of us dislike them because they're destructive to society. I'm sure I'm not the only one who went to a high school where athletics were more important than academics, and not going to the football game was worth a couple nitpicked points off on your chemistry quiz or some teacher who became a teacher solely to coach had you spend their class taking notes from a text book every day while they jawed around with other coaches in the back room.
I feel like sports culture deprives lots of regular public high school students of an education, and I don't think it's elitist at all to dislike professional sports for their contribution to this mess.
I love sports, but every time I watch or support them I feel like I'm destroying civil society and undermining democracy and helping to destroy the last vestiges of effective public education.
And I'm not elite or upper class.
