> thinking that something is capable of supernatural feats is not required for something to become a religion.
I basically agree, but I think the concept of "religion" invokes a lot of correlated things, and belief in the supernatural is one of the main ones. I expect most religions to differ from the 'prototypical' religion in a few ways, but I think sports differs in lots of ways.
(edit: or perhaps better, "beliefs about the supernatural". Religions say something specific. Atheists believe something specific. Sports teams make no claims one way or the other.)
> non-believers that believe so strongly in the non-existence of anything they haven't personally seen that they will hijack any thread that is remotely near using any religious word.
This seems like another example. I've seen that behavior from atheists and from religious people. I haven't seen it from sports fans.
People who dislike sports, on the other hand...
