[Marvel Comics] Why doesn't the public assume Spider-Man is a mutant like the X-Men?

People really hate mutants to the point of discriminating against them and saying slurs like "mutie" but even though Spider-Man gets bad PR it's like everybody knows he isn't a mutant.  Nobody calls him "mutie" or anything like that. When people see him swinging around, wouldn't the natural assumption be that he's a mutant?   Everybody seems to know he isn't one. How did they find out?

They pretty much do assume Spider-Man is a mutant in Ultimate Spider-Man, especially when the tabloids start publishing pictures of him and Kitty Pryde hanging out. 

However, Norman Osborne himself comes out and says he 'created' Spider-Man on national television at one point, and whether or not you believe that lunatic, it stands to reason if Osborne is responsible for all these crazy freaks coming out of the woodwork that use more tech than your run of the mill mutie, he probably did create Spider-Man somehow.
