I think about this often when it comes to my son(He has not shown any tendencies) more specifically how'd I react if he was and I can honestly say I'd be slightly upset. Though I know I would be supportive. In the end its ultimately thier chioce.
I'm not sure if there's a significant LGBTQ+ population on here, but I'm a part of that community. I don't believe that choice comes into it, because it would be easier to choose to be straight and/or cisgender. Some people's brains develop differently as they grow. There is some evidence for gender having a biological basis (Some journals talk about the chemical makeup of brains), but as for attraction/orientation, I don't know if there's been any research done on that.
