>>As for homosexuality, I do not believe that people choose to be gay, and pretty much all reputable research supports that. It's still not totally clear whether it's nature or nurture, but by fairly early on, people respond sexually to whichever sex they're attracted to. If it's not a choice, what makes it a lifestyle?
>Perhaps we can solve the above with genetic engineering.
You mean "solve" as in a "problem"?
Somehow I think homosexuality is not purely genetic, or else these guys would have vanished long ago by simply taking themselves out of the gene pool. However, there may be a predisposition, i.e. a chance that one's orientation is more or less wide. Don't see how that could be manipulated genetically without affecting something else along the way. Who'd take the risk?
