And your evidence that homosexuality is genetic is what? You pose this question as proof of something?
You make a great point, but that is an erroneous use of the term genetic. If homosexuality is inherited, it is better termed a multifactoral type inheritance. This is also the case with conditions like cleft lip and palate. They occur less that 1% of the time in general population, but occur at a rate of 5-10% in families with a prior history. That is about the same pattern seen with homosexuality. The word genetic technically means inheritance linked to a specific gene or group of genes and follows a pattern of inheritance predictable by the chromosomes on which it resides (sex-link or autosomal). Blonds will keep popping up no matter what we do to stop them.
