from a logical point of view, he is correct. when you think of baseball, basketball, football, hockey, skateboarding, bmx, whatever the fuck else, do you think of women on a level equal to men? of course you don't. wnba, tennis, softball, lingerie football might be more like it, but you have to be pretty regular/out to get huston to say skateboarding is for girls. it's overdriven digital political correctness.
ripping him for saying it is a basic mass combination of boredom, self-denial, and idiocy. skateboarding is rare for girls, yes, but believe it or not, woman's physique is not designed to endure that of man's. and if you have a rebuttle for that last antecdote, too, i will just go out on a whim and assume you have never considered the history of the world.
let the dude go, or come up with a ratio of professional female skaters to professional male skaters. the statistics might prove enlightening.
