Clearly you are not a George Carlin fan... my reference was to part of his act where he explains that Soccer is not a real sport because there is a spot on the ball, cycling (and running) are not real sports because because they are "just a way to get somewhere". (he also says Hockey is not a real sport because it is the combination of 3 activities, figure skating, playing with a puck and ... .well, the fighting you mentioned phrased differently).
In your quote of my post you missed the smily face, which was intended to show that I was kidding around.
Soccer and Hockey are very similar sports, I agree, in fact I assume they are both based on the same style of sport originally (players in lines, goals, concepts like offsides, etc).
That having been said, watching Hockey in the US and watching Soccer in the US is very, very different. Watching Hockey in the US you are seeing the best players in the world play in a competitive season (6 months). Watching Soccer (MLS) is about the 10th best league in the world (if that). You are seeing marginal players that probably could not even play in Germany or England or other strong leagues. Basically, the MLS is about a High-A league level with players too old to be called prospects (obviously there are some exceptions)
