I don't think you lead people to be gay or straight.
I do think, as the aforementioned examples showed, people can choose to be gay. I don't think they can be induced to be gay by being exposed to homosexual behaviors. I could be wrong of course. Stranger things have happened.

:
What I think the recruiting factor is about is leading people,especially young impressionable minds, to abandon moral character.
To subvert that resolve so that we have no boundaries for any behaviors.
Sick twisted films like, ''THE PURGE'', that had a sequel.
Mass murder OK'd for 24 hours for some ''reason''.
Seems like benign lame sorry example if entertainment,yet it imprints on weak minds.
Just like the hate film against Republicans during Trump's term. ''THE HUNT''. Hunting and killing members of the GOP.
It's programming designed to divide a country and stoke what is already depraved in depraved minds.
But sexual acts programming? I dunno.
Could make for an interesting social study.:)
