I like to see if there's any new arguments. There never are, but I keep hoping against hope that something interesting will happen (which is exactly how I feel when I suffer through a throwball or baseball game).
There are plenty of reasons not to like Soccer, as there are plenty of reasons not to like Hockey, Basketball, American Football or any sport.
There's no objective standard for what makes a sport good or interesting.
Again I would just say that a North American soccer fan using the sport's global appeal to somehow justify it's worth in this part of the world is wrong-headed IMHO.
Not saying that's what you're doing here but some people do just that.
