As a member of the LGBTQ community, I fully agree.
I’ve believed that we are a mix of nature and nurture for as long as I can remember, and it stands to reason that sexuality is a part of that. I also think the vast majority of people are far more sexually fluid than they would admit due to cultural stigma. Not everyone is bi, but I do think there’s a bell curve.
That said. I do also believe that people are born the way they are and the nurture aspect is more of a determining factor for how they express not who they are. I was raised and socialized as a straight male but realized in my 30’s that I’m queer and non-binary. Realizing that put so much context to the struggles I had growing up on a Christian environment and solidified for me that this is who I am, despite how I was nurtured. But had I not gotten out of the religion, I’d have never changed and just silently suffered and struggled until I died. My expression wouldn’t have changed who I am, only how I acted.
I’m not one of those ‘I hate children’ child free people, but I really love not having any kids of my own. There’s plenty of kids out there that need parental figures who’s need I can meet. My partner’s daughter is one of them, and I love the hell out of that kid.
But at the end of the day, I’ve still done better for the world by not bringing one of my own into it, for a multitude of reasons including climate change.
