OK, here I made the presumption that in a social group with high child death rates every sexual opportunity taken affects procreation rates.
At the very least homosexuality is a distraction. If there is no pressure on gay men to marry (a woman) and have children a proportion would not do so.

...I'm not sure you got what I said. No individual applies judgemental criteria. He may have been brought up to feel that certain types of people are an outgroup. Once he recognises someone as being of that type he will automatically feel animosity. (particularly if he is innately conservative, and not much if he is innately liberal).
Yes it does. You have overlooked that these are twin studies. The attitudes of the subjects is compared with their twin.Essentially all this study proves is that some people in Australia are homophobic and that generally age does not seem to predict if they will be homophobic or not and that heterosexual men men tend to be less favourably disposed to homosexuality than women or homosexuals.
This does not prove that homophobia, or aversion to homosex is innate to humanity.
For one thing many hereditary traits can find stronger expression in males than females and vice versa, eg height, aggression. (But I think there are also other factors accounting for the discrepancy).If this were the case then the discrepancy between men and women being homophobic would make no sense since both would have been born of equally homophobic parents into a presumably equally heritable homophobia.
Yeah, how else do you think we spawn, er, I mean, recruit?!
Yes it does. You have overlooked that these are twin studies. The attitudes of the subjects is compared with their twin.
Identical twins share 100% of their genes, non-identical twins share only 50%, adoptive siblings share 0% of their genetic variation. Identical twins raised together share genes and environment, identical twins separated at birth and raised apart share only their genes. By looking at the differences in correlation between each of a twin pair its just maths to work out the effect of genes and effect of environment on the average difference (variance) in attitude.
If the attitude was purely environmental you would expect the same variance between ID twins, non-ID twins and adoptive siblings raised in the same home, school etc on average. You would ID twins raised apart to differ as much as non-ID twins raised apart or any unrelated pair; - their attitude would totally depend on where they were raised.
This study shows pretty conclusively that there is a huge genetic influence on attitude towards homosexuality.

Face it: Human nature has a strong flavour even without the sauce of nurture.
That's absurd. Everyone is responsible for their behaviour. A date-rapist is not excused by his innate desire for sex, a thief is not excused because he was hungry, innate impulsivity does not get you off the hook for a road rage attack, a psychopath is not exused his murder because of his innate inablity to empathise etc. etc.hilaire said:Your last point indeed the overall tone of your last few posts encapsulate the basis of a defense to murder or assualt charges which would claim that natural aversion to homosexuals, homosexuality or homosex was "innate" and hereditary therefore at least partially absolving the individual charged of responsibility for having attacked a gay person. Even if there is some validity to the research you are so conviced by there is no moral value to it
Fair comment. However, Australian society is similar to W. European and American societies. And similar twin studies were done in the UK and US with similar results. And we are talking about human nature here and now.Again no it doesn't. This twin study shows the attitudes prevalent in one part of the world at one particular time, at best it is a snapshot. It does not show that humanity has a genetic propensity to hold a specific view regarding homosexuality. History and anthropology completely contradict this view in any case therefore at best these studies show an anomaly that must be investigated but it does not show a conclusive pattern which proves your point.

There is nothing moral about discovery itself, however the application of knowledge is definitely moral issue.

But how would such a study play out in another culture? The environmental component is unmasked in this study because there is sufficient gradation in attitude across the environment to be able to compare differences in enviroment whilst controlling for genes using the twins, whilst comparing the effect of genes whilst controlling for enviroment using the same family.
In societies where attitudes are uniform, say becuase of a powerful cultural effect that regarded homosexuality as normal, not only would any innate aversion be more effectively desensitised, and any remaining variance would be 100% due to genes. Similarly in a uniformly culturally induced homophobic society any remaining variance would be 100% due to genes. You'd have to do the study.
In fact I don't believe human nature throughout history has changed and variance in attitude across time is mostly due to culture.
Stronzo was making the point that media entertainment portrayals that are bias against gay sex perpetuate the cultural effect of that bias in the audience which, in turn, the media seek to satisfy, in a vicious cycle, which is true. I merely wished to point out an underlying factor. The evidence is out there, whether I point it out or not.
My poor english. Gareth Thomas, 6'3 220llbs warrior of the international rugby stage has just come out. He was married.
This is the rub. Most homosexuals hide in plain site as they are not stereotypically gay (effeminate, campy, etc.). Great point, BTW.As far as I know, Gay men don't have to wear pink crosses, so I was asking how you are suppoesd to revile a group that you can't identify.
The only thing that you could try to assess would be revulsion at homosexual acts. This would be a behavioural study and attitudes to behaviour are almost certainly cultural.
