Hey, I just go by what the majority view states is a fan and a fanatic (that being the dictionary meanings of the two) because that's the only true way you can really "define" one or the other. It's really not semantics when you look up the definitions. A lot of people can easily say, "Well that's just the dictionary." But you have to have some kind of standard and for me, as well as the majority of the country, that IS the standard, so that is what I base my arguments over definitions on.
You can call them supporters and I can call myself the President of the United States.
