Yeah, that's what was taught to me in psychology class years ago.
Everyone is born a blank page, blah, blah.
I knew a psychology student intern that was planning on raising his newborn in a socially sterile environment, void of mother/baby contact. Similar to how condor hatchlings a raised.
After getting out in the real world, having 3 kids of my own and friends with kids, I realized people are born with at least certain personality proclivities.
My 3 kids were very different, growing up in the same house, same parents, etc.
I can't see how they can be so different unless there is a genetic factor.
I believe many gays are genetically predisposed to their attraction.
Some choose it. It's an 'in' thing with girls I understand.
Modern science attempts to come up with a story that holds water but in the face of the infinite nature of this universe it only scratches the surface and having solved one puzzle moves on to the next mystery.
