I have a gay brother and a lesbian sister. On different occasions, both have told me that their sexuality was something they became aware of, not something they chose.
My brother said that considering the grief he suffered while concealing, accepting and revealing his true self (especially in his awkward teen-angst years) there was no way he could imagine that anyone would choose to be gay. He said he probably would have committed suicide if our parents had rejected him on coming out.
Furthermore they both said this is not something that can be caught or forced onto a person. https://theporndude.com/shemale-porn-premium-sites
So the notion that gay adoption should not be permitted (because gay parents risk infecting or corrupting an otherwise straight child) is beyond absurd. It is in line with the mentality of aversive conditioning and straight camps, exorcism and bloodletting.
I know I’m running off topic here, but a child does not really need a one-man one-woman nuclear family structure. Although that structure can work well it is no guarantee that a family will be functional enough to meet the needs of a child.
A child needs just 3 things:
Sustenance
A loving environment
Structure
