I'm really confused as to what you're trying to say. If you're pretty you shouldn't pledge a less popular chapter?
That email was less about physical beauty than it was about rules and regulations. My chapter's fb group (let's just say my alma mater was the polar opposite of USC) thought it was awful, until I explained the size of these chapters and this rush. It's honestly more like wearing uniforms at school to keep the focus on academics. I didn't think anything in it was over the top or rude.
