What causes someone to be gay?

Davey Wavey posted on his video blog that he is concerned that homosexuals will go extinct because fewer of us are forced into heterosexual marriages and bear children. I have a different view and made this video to discuss where gays come from.

Yes, this video is based on actual peer reviewed scientific literature. :)

I think we should look very cautiously at some of the studies described in these videos. The results of many of these studies are far from clear, and results are biased so that evidence supporting the hypothesis is kept while anything otherwise is discarded. No, there is no sufficient evidence pointing towards the 'cause of homosexuality', just as there is no evidence pointing toward the cause of not liking chocolate ice cream. Suffice to say, sexuality is fluid and homosexuality exists

@z120p well, a lot of people believe evolution isn't real, ignoring evidence that supports it. They also believe global warming isn't happening, ignoring the evidence for it, including 8mm sea-level rises each year. You're more than capable of using Google and finding the peer reviewed research itself. The purpose of all my videos is to encourage people to think.... Seems in your case it only encouraged you to spout off assertions with no research behind them...

The brother theory also supports the idea that there will be fewer gays in the future, because couples (particularly in developed countries) are having fewer children and there is therefore less likelihood of a gay younger brother, as the children stop before the odds increase. As my favourite kid in the whole world is a (gay) youngest boy, I'm glad his mother didn't stop too early. :)

@rivenrock well, there is also the psychological theories that hold 'helicopter parenting' leads to homosexuality in later life too. :)

Don't worry - we're here for a while yet...

HAH! You are awesome!! How do you think we ALL got here? (It wasn't a PINK COLORED STORK!).And we will continue to born for the next year after the next year and for just as long, year after year, as those straight babies will be, as cute as we ALL are as newborns!! ALL babies are beautiful! There are few things finer than having a new baby in the house, and introducing yourself and getting to know your baby.

@pacific707 I find babies terrifying. They're small and helpless and seem to look at me if they want me to keep them safe and developmentally moving in the correct direction.

*shudders* terrifying... :)

@markuskeats Believe it or not, the citation list of wikipedia's article on Biology and Sexual Orientation is better than my list :)

I'm unable to post a links in the comments here, but if you jump on wikipedia and search for Biology and Sexual Orientation you'll find it :)

Good video, but i think the separation between physical, emotional and spiritual gayness needs to be mentioned.

for instance, someone doesn't need a physical attraction towards the same sex to be gay, sometimes it's only a mental or spiritual attraction. If i start my trans answers soon i'll tackle that from my opinion, but I'd like to hear yours. :)

I know that what causes me to be bisexual is my penis. It has a mind of it's own......which kinda makes it sound like a 50's sci-fi movie but anyway.

[masterseries2012]

Oooops, that should have been should....then babies. There!

[masterseries2012]

Oooops, that shuld be babies!

[masterseries2012]

If the straights hate gays so much... why don't they stop having gay babaies?!?

[beversfamily]

The greater question would be... what is the cause of heterosexuals? Why don't we ask THAT question? BECAUSE HETEROSEXUALS THINK THEY'RE NORMAL AND HOMOSEXUALS ARE NOT! Get over that part of the theory, and we can all just accept that we are who we are naturally!

@DifficultNerd Reply 8: As a last note I'd like to remind you that this 'quest' for seeking a 'cause' for homosexuality, in light of knowing that it exists, stems very much from a philosophy which continues to see sexual expression apart from heterosexuality as an anomaly. That's why there are few theories on the cause of preference for asparagus, because we are indifferent to whether one likes it or not.

[z120p]

@DifficultNerd Reply 7: Perhaps one day a cause for homosexual orientation will be found, although as you have implied in your video, I doubt it to due to a 'single' cause. But I also believe that won't be until we fully appreciate and recognize that homosexuality and heterosexuality are not fixed concepts, and so causes will probably only point to certain 'predispositions' to certain sexual behavior, not concrete socially constructed identities and labels.

[z120p]

@DifficultNerd Reply 6: It amazes me that there is obsession with identifying a 'cause' of homosexuality. We acknowledge it exists, just as we acknowledge that a disliking for asparagus exists among some and a liking for that same vegetable exists among others. We can observe that a person who dislikes asparagus may experience a negative, neurally traceable response to asparagus, and that suffices. Why don't food preferences deserve the same attention to causation?

@DifficultNerd Reply 5: Instead of seeking out the cause of 'homosexuality' (I make note that no one ever really goes about seeking out the cause of 'heterosexuality', it's biological function in the evolutionary process is taken for granted), perhaps it would be better to start out by focusing on how sexuality is expressed, on learning whether sexual diversity is compatible with evolutionary theory and why, and then exploring whether our categorization methods are too limited..and then move on

@DifficultNerd Reply 4: That is not to say that individuals may experience a dominant attraction to one gender over another, and indeed many bird species (one example) have shown just that. Yet when I said we must be cautious I said so because I do not believe that any of the theories that have been developed come anywhere near to explaining something as complex as sexuality; and often come about by a false notion that sexuality is much more simple and black and white than it really is.
