* Studies on identical twins all come back with no evidence of a genetic cause.
* Scientists can't find a gene common to all homosexuals as the cause
* Those with the "gay gene" would be very unlikely to pass it on to offspring
Yet 1 out of 10 according to some studies identify themselves as homosexuals. The preponderance of the evidence points to a non-genetic cause no matter how much you want your "genetic theory" to be true. Homosexuals aren't a genetically unique "race" of people. They're normal people that ended up with abnormal sexual preferences.
