A high percentage of men engage in homosex while in prison. The vast majority of them go back to women when they are released.
They don’t (mostly) “become gay” due to their prison time.
There is very limited evidence as to how many inmates engage in homosex. It’s probably somewhere between 20% and 60%.
Again that begs the question - what does “being gay” mean?
Is it engaging in the act, or a defining aspect of the person?
I saw a prison documentary, a man saying exactly what Carson said, he came in straight and left gay...was rearrested for male prostitution.
Sexuality is not as locked-in as many would have you believe. There’s been studies on identical twins, where one is gay and the other isn’t. If it was purely genetic this couldn’t happen. They also found that over time many of the “gay” twins actually turned more hetero, many to exclusively hetero - leading to the conclusion that there’s probably more ex-gays out there than in the current gay population. Although the left will not allow any discussion on ex-gays because they know it is true.
This is all taboo though and not allowed in discussion. If real science on the topic were allowed it would be at odds with the gay narrative.
