Freud said it is part of sexual maturation to be first pre-occupied with auto-eroticism, then perhaps a fleeting interest in and identification with others of the same gender, and finally sexual maturity that enables one to have a fulfilling relationship with the opposite sex.
"Recruiters" seek to suspend teens in the phase where they are curious about their own bodies and others like them. They seek to have teens quickly identify as homosexual if they have even a scintilla of attraction to anyone of the same sex for any reason and never move on to heterosexual relationships.
Yes, Freud said a lot of nonsensical things that have since been discredited. Few modern psychologists take Freud seriously.
I never had any sexual interest in or identification with others of the same gender, even fleetingly. I was born an extreme heterosexual. Your "recruitment" theory only works with bisexuals. Sorry, it still amounts to coming on to them for the purposes of having sex (just as I did with girls), not some kind of international gay conspiracy to expand their ranks.
