I really don't think she's arguing that she had those experiences because of skateboarding, but rather illustrating that these experiences exist within skateboarding - despite how welcoming, counter-culture, or egalitarian as skateboarding pretends to be or is marketed as. And it's a point that needs to be made. People are still more upset that skateboarding will be in the olympics and cry that it's not a sport, but still celebrate, ignore, or undermine the jock shit she describes.
