Wow, 100% not true. Have you ever been outside of North America? American football is a joke in Europe and the rest of the world. That's one reason why NFL Europe flopped. Some people go out of curiosity and the violence, but a lot of the people there are Americans (military etc.).
You are way off here.
I have seen the superbowl in Europe a few times. They show it live, because it starts at 11pm or later local time. Made for a very long Monday at work
I do wish American football would have been named something else. Particularly since World football had been in existence long before American football. But it is what it is.
You don't like soccer, cool. A lot of Americans don't. I enjoy soccer and the Bills. The two are not mutually exclusive.
