Except that's a completely different point of discussion, and no one is making the argument that you seem to have concocted inside your own head.

If people were responding to American Football fans smashing up a bar or something and saying "this never happens in Europe, our fans are much more civilized", then you'd have a point - but nobody is saying that.

It's about this baffling practice - which honestly as a non-American I'd never heard about - where apparently it's commonplace to make people train in hot weather and a lot of gear, and for a long time, with little to no water. That's what people are so surprised about, mainly because it just seems so counter-productive for athletes, not to mention bordering on barbaric.

Football players in Europe at a club's youth academy (which would be the equivalent to College Football in the US) aren't being forced to train without water, and certainly there is no culture of it being a somewhat established practice. It is baffling to non-Americans - and presumably plenty of Americans too - which has absolutely nothing to do with how fans of European or even South American football teams conduct themselves.
