Because thats the way they were brought up. With people who had some kind of authority telling them its something you shouldnt do. Plus, they never used their own brains in their life.
^bah Carrie Prejean did several tv shows lately to promote her opposition to gay marriage and defend herself as to why she answered that to Perez at Miss USA.
and i do read Perez daily, i won't deny it. does it bother you that much that i use a picture from his website to discuss someone who has been discussed elsewhere than on Perez's site? i don't judge what you do in your free time.
So she opposes fruits getting married, so what? It's so annoying, its like if you oppose anything that is 'Liberal thinking', you're seen as some kind of monster.
