yes some truth that applies to certain PEOPLE not a entire FANBASE or RACE.
Its generalizing plane and simple.
Either way your try to slice it its wrong and not right to try to lump others together into a certain category despite the fact that they may not share that stereotype with others.
I could walk up to a black man and say "hey do you like chicken?" and he could say "no, I am actually not that fond of it".
Would it be right for me to ignore what he said and still put him in that category simply because the generalization holds SOME truth to it?
