From Gay Rights to Nature vs. Nurture. Man, what a thread.

Honestly, I can see his side with the whole "Because my parents raised me that way" arguement. If you're told something since you were young, it's rather hard to think of it as anything but true. Children grow up thinking that their parents are always right. Of course, some people have the sense to actually think for themselves and realize that they aren't always right, and decide to form their own opinions.
