Yes I did, it is good that you remember that. Now all you have to remember is that I did, and that I am actually defending my premise with other people that disagree with me.
You have yet to produce any evidence to support the claim that people choose who they are attracted to.
Were you attracted to both men and women and flipped a coin?
I don't recall a choice. When my friends were mooning over Shawn Cassidy and Leaf Garrett, I was crushing on Kate Jackson and Julie Andrews. In kindergarten I went to Catechism because the girl I had a crush on went. I did not choose these attractions. I do choose to act on those attraction. That's the only choice (and the reason "conversion" therapy is an abject failure, harmful and renounced by all major medical associations.)
Where is your evidence that it is a choice? You've provided a search string to twin studies, which do not support any "choice" assertion.
The mounting scientific evidence points to a predisposition regarding orientation. Gays will tell you that they don't choose their attractions. Reparative therapy has a success rate of less than 2% and those that are "successful" admit their feelings and attractions don't stop, only their acting upon them. What motivation could drive the insistence that orientation is a choice?
