I also read the article on the lack of any "gay gene" and what struck me is the obvious lack of understanding of genetics by the author. While many of the public assume that human characteristics are determined by a single gene the reality is that most characteristics are determined by a combination of multiple genes.
For example, there are about 20 genes which when some of them occur the combinations can produce ADHD, OCD, dyslexia, and in extreme cases bipolar and schizophrenia all to different levels. The same applies to height skin colour, weight etc.
That there are a combination of genes that can point to sexual attraction means that there is a clear link to genetics as a causal factor and also explains why same sex attraction is unlikely to die out as other combinations of these genes may produce individuals with qualities far more beneficial to the continuation of the species.
