It has nothing to do with disgusting. Two men having sex together doesn't produce offspring that could potentially have genetic damage due to inbreeding. Hell, I breed dogs and cats and WE avoid inbreeding in our ANIMALS because it causes so many health problems.
When a couple does something that they know will produce a child with a higher percentage chance of birth defects, they are indeed involving the government - especially if they use health care provided by a public system. It's a give and take; we need to decide HOW damaging a thing is, not how "disgusting" a thing is.
If you want to argue that gay men having sex together is somehow damaging I don't agree with you; but at least the argument would be able to get started. "Damaging" is something we can quantify, "Disgusting" is just something that elicits a feeling.
Fine. Let's talk "damaging."
Technically Anal Sex is incredibly high risk, as it's receptive form is the most efficient way of STI transmission. Much more "damaging". Do we ban that? No.
Also, take a genetics course, PLEASE, because you're wrong. Firstly, DNA is not "damaged" when you inbreed, you simply have less diversity in terms of your genetic pool. It does NOT automatically increase your chances of genetic defect, it just means that if both your parents had a chance, because they're from the same family, then your chance is slightly higher. It would be the same if two completely unrelated people with those same potential defects had a child.
Also, please don't compare dogs to humans; there is a reason why animal studies are never accepted as evidence for biological plausibility in Hill's causal criteria. It takes GENERATIONS of inbreeding in humans for there to be a significant chance of that potential defect occurring. As in several; 6 or 7. You know how long that is these days? Almost two centuries of inbreeding.
Do you understand? This is not a public health issue. It's a cultural one.
