Still not sure what the issue is.
A. They should read the article as it specifies the character isn't a Slayer, just a normal guy who slays vampires and would like to be a Slayer.
B. A gay character. Willow, Tara, Kennedy anyone?
C. A male
gay character. If one finds a female gay character acceptable but not a male one, then I'd say that's maybe more stupid and offensive than just flat out not wanting any gay character.
That is all.
