You can brainwash people into wanting to be gay. Train their brains to chose the wrong path. One could increase the amount of soy in a man's diet to make him more feminine, and poison him through his food and education to make him dummer, number and one could ruin the foundation he was raised on so the only person he has to turn to is the state. If you ruin everything about a man's life, if things line up just right, some men can be "turned" gay, though it wouldn't be a genuine gay guy.
