Why do people do this?

I try to be a positive presence here and keep a zip on my lips if I don't have something nice to say, but.... I am seriously so sick of messages like this! Do you understand the message it sends? It says that no person is worthy of being spoken to unless they meet your criteria of beauty or sexiness. I say that is bullshit! The most beautiful people I know, are beautiful because of who they are... inside! If you're too shallow to look past whatever physical attributes you've decided a person is lacking, you are truly missing out on some absolute treasures! And you might as well block me now, because I'm nothing worth looking at.
