There is no discrimination. Marriage has never been a right for members of the same sex. In all the cases you mention, opposite sex has been the determining qualification for marriage. All of the genetic defects you list are apart from the identity of marriage. You are demanding that a defect that distorts the core identity of marriage be equated with marriage. It is nothing more than a forced imposing of a imposter relationship on the foundational relationship of society. Gays still have every right to pursue appropriate rights for civil unions.<quoted text>
Ok, let's play a scenario here... Let's say that being gay is a defect. If it is, then why discriminate against gays? People with defects get married every day. Dwarves get married, theirs is clearly a genetic defect. I have seen 2 people with Downes Syndrome get married, theirs is clearly a genetic defect. I have seen people who were previously circus freaks (and I mean that was their job) get married, they clearly have defects. Why should all of the others with their obvious defects be allowed to get married, and gays are discriminated against?? If gays aren't allowed to get married then all of those others who are "defective" shouldn't be allowed to marry either according to your reasoning.
It is one thing to admit you have a genetic disorder. It is another thing to respond realistically to the consequences of that disorder. You are claiming it is maybe a difference, and with no real distinctive impacts. Very close to pure denial.
I have three nipples. I don't hate myself for it, I had no choice in the matter. I have faced numerous consequences through my life because of that (as you can imagine). I have never pretended that is normal. Some consequences have been painful emotionally and physically. But my responses have made me a strikingly unique person in numerous good and positive ways exactly because of my 'defects'.
