Superficially it's a problem if homosexuality is genetic - if the difference between people's sexual preferences is genetic - because at least a pure homosexual would be unlikely to reproduce and therefore pass on the genes. So the first question you ask is, is it actually genetic, and the answer is probably to some extent yes.

I am not an enthusiast for diversity of opinion where facts are concerned.

The evidence for evolution is so compelling that the only way to save the creation theory is to assume that God deliberately planted enormous quantities of evidence to make it look as if evolution had happened.

Explaining is a difficult art. You can explain something so that your reader understands the words; and you can explain something so that the reader feels it in the marrow of his bones. To do the latter, it sometimes isn't enough to lay the evidence before the reader in a dispassionate way. You have to become an advocate and use the tricks of the advocate's trade.
