I think it’s a combination of choice and biological formation. But what I’ve always thought is it is more empowering to say it is a choice of where you direct a neutral sexuality.
See if it’s seen as just born that way, that’s open to two negative possibilities. One, it means that I as the individual am helpless, just throwing up my hands cause I’m born this way. Which then means that we have to accept other paraphilias that may not be as tasteful, they too can then argue they were just born that way. Who distinguishes a paraphilia from a sexual orientation?
Second, as we get closer and closer to identifying and modifying genes-DNA we open ourselves by acknowledging there’s a biological cause to have those with the resources having geneticist aim for the biological causes of undesirable traits. We can already isolate eye color, hair color, height, weight issues. Within 10 years we’ll be able to readily control those characteristics, why not then sexuality if you can identify it? If you follow the logic of why you would you would just have to look at the “Out” population and how people, LGBT people are treated in various countries. If you’re Russian and have the financial means would you want your son to be born gay? What about Pakistan? Or Iran? Or Accra, Ghana, one of the most fundamental religious places on Earth? Imagine how life is there for an LGBT person. A loving parent, with the resources might say, no, it’s too heavy of a burden.
What about here in America, where genetic alteration falls into two area—-somatic and germ line or hereditary future?
Just because equal rights are legal law doe snot make them socially adhered to. We only have to look at racial imbalances to see that.
