I wanted to add something. It is true that the soccer fanbase is a vast ocean of irredeemable chuds. But there is a small clubs whose histories are rooted in left wing thought of some variety. Liverpool for example as an area is Labour leaning because they hate Thatcher and her austerity. Celtics are republicans and hate the Queen. These elements are unfortunately being watered down slowly as football has become corporate and Europe becomes more reactionary but it’s something that was there.

The only thing similar I can think of when it comes to American sports is that the Green Bay Packers have an interesting ownership structure. Apart from that I haven’t heard of anything like that.
