Well, if it's partly biological, then it is genetic. "Genetic" doesn't mean that it can be predicted with a Punnett square; there are probably lots of complex, co-acting genes, and many of them just have to do with hormone production, which as you say is also influenced by environmental factors. Other types of spectral traits have been proven to be genetic, even if the genetics are poorly understood.

Unfortunately, I've only been able to read the abstract, so I can't confirm or deny the allegation of "volunteer bias." Also, the first bullet point on that blog is just plain wrong. Have they ever heard of recessive alleles? Or have they heard of the fact that people with homosexual tendencies have had plenty of heterosexual sex throughout history due to societal pressure?
But then I realized that I don't care. Like I said, I'm happy that the conversation has progressed beyond the point where people yell "OMG U CANT BE BORN GAY ITZ A CHOICE!" Caring about the extent to which homosexuality is biological only serves to imply that people should "control" it if it isn't. Bottom line is that we shouldn't police or judge others' sexuality, no matter how they arrived at it. I only care about it in the sense that I'm a science geek and it's rather interesting.
