I don't know if that definition of fan boy applies to you. I don't remember the earlier thread as well as you seem to.
I use fan boy to mean someone dedicated to a particular team, person, or idea to the exclusion of reason and rational thought.
The guy who says "X is the best, better than everything else, for everything, perfect for everyone in every situation and nothing can ever be as good as X". That's very different thinking for "I like X, but Y seems to have an advantage. Let me learn more about what Y does right and see about improving X."
