Tbh, I have no association with the LGBAlliance so I have no idea what kind of agenda they're trying to push or what the people involved in that organization are saying about GNC-ness, so I can't respond to any of those points.

However, your last point is blatantly incorrect and honestly offensive. People are born with sexualities. People are born gay and bisexual just as people are born straight. I had crushes on girls when I was 6 years old. I knew I liked only girls by the time I was 9 years old. I didn't start puberty until around 12. The sexual attraction doesn't start until puberty. But the orientation is still there. How the hell was me having a crush on my female friend at age 6 an expression of physical abuse??????? Straight people can talk about their stories of having crushes and holding hands with the opposite sex when they were little kids and it's regarded as normal and cute but suddenly when gay people do it it's physical abuse????? I was never physically or sexually abused as a child, but I still had gay crushes. Many, many, MANY gay people have similar stories, and knew they were gay before puberty. Explain that please??????
