1. The hell does this have to do with our game?
2. It's "fear of the other" not "fear of stranger".
1. we were talking about how various "ism" aren't rational (but actually are) in regards to humans, in this context it had to do with why people would hate mutants, or to my argument, would not hate mutants.
My point was that public sentiment of mutants would not play out the way it does in the game or the comics, human fear and hatred of the different has various aspects to it that stems from biological determinism. In the comics, mutants are seen as a separate race when any honest biologist could not classify them as even a separate sub-species.
Someone like Jean, Kitty, Piotr, Emma, and Null would not face the type of discrimination and disgust response they are shown to. Ones like Kurt, yes, but not the human looking mutants. If anything there would be resentment towards mutants like Null from within the mutant community since mutants like him get the best of both worlds.
Someone as good natured as Kurt wouldn't be hateful like that but many others would. Humans on the other hand would see them as desirable.
2. Phobia = aversion, repulsion, or fear depending on context. A raincoat is not afraid of water but still repeals it hence it is hydrophobic.
Xeno = foreign or strange. Example: xenolith, a rock formation that is strangely out of natural order with the surrounding sediment and is derived from elsewhere, or in other words it is foreign to the surround rock.
Emma has also been portrayed, rather sweetly, to actually appreciate honor and nobility when she fell in love with / got a huge crush on Spider Man after reading his mind when she basically forced him to help her rescue a girl (ironically she could have just asked). In her own words "It was beautiful in there" when she spoke about his mind later on.
Of course i don't believe anything ever came of it.
That said, she could be set to appreciate a heroic Null over an angry one. (Of course that may annoy some folks)
She likes selfless people, even though she herself is very selfish. Some explanations of why are more charitable than others.
