Its pretty much hitting at an empty wall.
Guys seem to do this to look superior or, in my terms, be an Alpha Dog. Sharing researchographic sites is, apparently, a sign of masculinity. However I do not support this, it is quite prominent. The guys who go around saying things like this are usually the ones who, really, are virgins despite the fact that they may brag about loveual endeavors.
it disgusts me. It really does damage someone's self-esteem, too. If a girl finds out that boys are rating her as slatternly or not loveually attractive, it can really cause things to go wrong. Once again, the empty walls. If you put too much pressure upon somebody, sadly, they can eventually cave and and can see themselves as others see them. I've seen it happen before and I've been witness to people actually rating others.
Overall, this strongly disgusts me how people can get a group and order them. That, in my opinion, lead to the Holocaust. And being a Holocaust descendant, nobody wants to see this discrimination happening. It will just build tension.
