OK, but what about sister and the eight-year-old girl? By this logic, you could say that because incest is usually forbidden by religious tenets - just like homosexuality - that any goverernment laws forbidding incest should be thrown out?

And what does fear have to do with this?
There's a difference. Homosexual acts between consenting adults don't harm anyone, whereas sex with minors or relatives is extremely damaging to those involved.
