Anybody with a brain (which lets out most Liberals) knows this is the case.
"I was born this way" is just an excuse for abnormal and abhorrent behavior.
My wife and I were just talking about this subject two days ago. My female cousin, same age as me, was a normal teenage girl in high school. She had lots of boy friends, went on dates, and spent lots of time talking to boys on the phone. She was pretty and she was happy. I did lose close contact with her after high school, but I know how her life went after that. She was married which ended in divorce. She became depressed and eventually moved into some type of communal living arrangement with other women somewhere in New England. She announced she was gay. She committed suicide. Was she born gay? I don’t believe it for a moment. She was weakened by events in life. She fell under the influence of bad people. Her life became even more messed up and ended badly.
That is the idea, attractive but totally without empirical support, that a given outcome has to have a single governing cause.
In reality it is likely that homosexual behavior, like most other behaviors, can be generated, conditioned, and reinforced, by a variety of stimulus domains. IOW, you can get to be homosexual through any number of routes, many of which have probably not yet even been identified.
The pressure to determine a single cause is political, not scientific, and we all need to keep that fact in mind.
