If inducing trans and gay were that easy it would be as easy to cure it. It isn't.. Trans is so incurable that despite the side-effects it is considered much easier to change the body than the mind.

But I agree with your second paragraph. I'd say that there is such a thing as information hazard. You need anti-memes for such. And best before being exposed to the info-hazard. Kind like an innoculation. At least as a minor when you don't have a sufficiently general mindset to dispose with such ideas easily (stronger immune system).
