Admittedly a homosexual can be conditioned to react sexually to a woman or to an old boot for that matter. In fact both homo - and heterosexual experimental subjects have been conditioned to react sexually to an old boot and you can save a lot of money that way.
It is bad policy to regulate everything... where things may better regulate themselves and can be better promoted by private exertions but it is no less bad policy to let those things alone which can only be promoted by interfering social power.
