Why are females no shallow?

like they hurt ugly males feelings they turn them down and they act like a ugly male is not suppose to get a girlfriend or even live for that matter maybe its just where i am at in baltimore seems like a lot of girls go straight for looks. Like i once had a slut over my house to sleep with her but she sleep with 3 friends of mine and 2 in my room and the other in his house and wouldnt sleep with me cause im ugly . And on facebook girls are so mean to me cause im ugly i say hi to a girl she say leave me the hell alone ur ugly. As well as in person the girl embarred me infront of alot of people saying ur ugly out loud for lots of people to hear it. Its seems like girls are just naturally mean to ugly people i hope to god i get a girl one day but these girls are making me lose my hope. WHY ARE FEMALES SO SHALLOW TOWARDS MALES ABOUT LOOKS?
