I'm going to refuse couchsurfing service for ugly girls
That seems a little rude.
I care for pretty girls, I love them. But ugly women are disgusting.
Don't you think it's ridiculously shallow and rude to accept people solely based on looks?
Oh I didn't know I was being rude.
I think you need to reexamine your morals. It's really cruel to judge someone for something they had no control over, such as their looks.
