Have you not noticed the point that has been mentioned previously regarding birth defects in incestuous relationships, now this may not apply a same sex (or one in which one partner was infertile) incestuous relationship however it still applies to other incestuous relationships and explains why incest is illegal as it would be discriminatory to allow one type of incestuous relationship but not others.

The major difference between the two is that homosexuality is a sexual orientation. Somebody who is gay is exclusively attracted to members of the same sex, therefore without being dishonest to themselves and their partner marriage at is not an option at present. As far as I'm aware there is nobody who is exclusive attracted to their own siblings, nobody is being denied equal rights by virtue of not being allowed to marry their sibling. This is why the comparison between same sex marriage and marriage between siblings is such a terrible one.

You sound like a playground bully calling people gay as if it's offensive.

If you really got that from what I posted, you are even more stupid than I had previously suspected.

If you listen, you might hear the woooshing sound overhead.
