But he's right. Don't be those guys. They're worse than the guys who freak out at Youtube posters or chicks on Bodyspace and show these poor young women an ugly side of what they want to do with their lives and bodies. And, often, frighten them right out of that lifestyle.
Plus, you know, it's just plain f**ked up.
