Because its hip basically
This is circular. You're basically saying something popular because it's popular. You don't think people have the ability to actually THINK about a subject and form their own opinion?? No, it's just that everyone's a sheep and are going with the herd. If that was the case then there would never be change, and everyone would remain bigots. You'd never have civil right movements for women and black people.
Besides... that's not even what I was asking. I was asking that particular poster why he thought people think "evolution proves the bible wrong, therefore it's okay to be gay"?
