This "outrage" mentality is getting really, really old. Everyone is "offended" by something.
As for this Spider-Man stuff, I don't have a problem with it. This is very common with I.P.
If you don't think Disney has a set of rules for Mickey Mouse and company about how they are to be portrayed, you're mistaken. Same with Toho and Godzilla.
So he's white and hetero. BIG DEAL. There are black superheroes and gay superheroes and I don't have a problem with them, nor guidelines for those characters to "always be black and never heterosexual" if that's the way the companies ie; owners of the I.P. want the characters portrayed.
Frankly, I'm outraged by the outrage culture rampant in our society. /sigh
