It's my bit as a boorish American who thinks soccer is a second rate sport.
But it's just a bit. The only tickets to professional sports that I've purchased in the last ten years were to Soccer matches. Women's to be precise.
Fair enough; it just seemed an odd way to have a dig at football, since it plainly is a professional sport (3 of the 5 highest paid athletes in 2020 are football players, apparently). Second rate is a matter of opinion, of course.
