You forgot "soccer's a sport for them pretty boy eye-talians that fall over all the time". That'll cement your American status.
Honestly, I do a terrible job of not liking American football. I own jerseys for New England players, watch their games, and went to a game this year (and enjoyed the fuck out of it).
Really, I don't like it that much. It's very low on my list of favorite sports. But after my dad moved out, we only really saw each other on weekends, so we hung out and watched football. It's a big part of why we're closer now than we were when we lived in the same house.
