More than likely, many people who are abused tend to be attracted to abusive people until they can heal. My two cents, fwiw.
I agree that at least some people who are gay are born that way. Growing up, my family had another family that we were very close to. The other family had a boy my age named Miguel. I was always being told to play with Miguel, but he always wanted to play dishes, or color. When we were supposed to start at the church kindergarten together, I remember asking my mom what was wrong with Miguel. She told me he was just different.
Miguel got married and had a daughter. When his daughter turned 10, his marriage fell apart. He told me that he had known he was gay since junior high, but had just tried to make it go away. Didn’t work. He is now single and working as a lawyer. He has never had a gay relationship, but says he is 100% attracted to men.
The point of my post was not to argue with your belief, even though I disagree with it. The whole point of my post was that rape is not going to make a “gay” woman go “straight”. If anything, the opposite will happen.
