The question that makes fundies hostile

[Optimistic Mysanthrope]

If gay people can't/don't exercise choice, (in the same way as bi-curious ppl do or celibate people do, or heterosexual male prisoners do, etc. etc.) then how come some gay people choose to try gay conversion therapy???

If being gay is a choice, why would they need to try gay conversion therapy? Why not just choose to be heterosexual?

Leaving aside the question of whether such therapy works, there are some gay people who exercise intent.
And that desire or intent shows that such people have conscious volition.

A person who has no ability to choose their sexual preference would not have the capacity to contemplate such an irrelevant thing.

Some people contemplate seeking psychiatric treatment. They have a desire/intent and therefore they have a conscious volition. Does this mean that mental illness is a choice? Of course not. Having the desire to change an aspect of yourself does not mean that you have the capacity to enact that change. I might desire to become a giant panda and go to great lengths in order to become one, but to say that the only reason I am not a giant panda is that I have chosen not to be a giant panda is patently absurd. Only a fool would think otherwise.

If you want to see gay activists go berserk with the No True Scotsman fallacy, just ask them how come a person can get married to the opposite sex, have children, and wait 20 years to finally decide they are gay?

Maybe one day you'll realise why that is a malformed question. I doubt it, but you never know
