If they are born that way, then it can be cured, perhaps genetic therapy. Or they can be identified and aborted. Ironically.
Personally I think “Same Sex Attraction” is a partly due to exposure to hormones while the brain is developing. Whether or not one acts on it is what makes a person “gay” or not. For instance someone can have a biological attraction to males who is male. But that doesn’t mean they actually have to act upon it.
I think that in the future there could be therapies involving reactivating certain brain cells to “reset” the part of the brain that handles sexual attraction and it may be possible to remove the tendency towards same sex attraction from someone’s brain. I think the milder cases can be cured using conventional “gay conversion therapy” as the brain is able to re-wire itself, but not it seems hit or miss.
There could also be cases where someone is attracted sexually to “everything” and those people usually end up being all sorts of perverted....
I think society is to blame completely. They see an I feminists boy and constantly make fun of him his entire growing up years and when you are constantly hearing ‘you are a fag’ ‘you are a queer’ ‘you are gay’ for 18 years from school mates. The kid probably starts believing it. Another thing adults do is start pointing out such and such is gay. For example, Hillary Clinton. She has never said she was a lesbian, but we constantly say it to the point where she gets comfortable enough to say ‘well everyone believes it, what the heck’ and the next day she is on the cover of time magazine as a hero. The heterosexuals made this problem and we need to fix it some how.
