OK, let's discuss infertility then. If there were an identifying trait for those that are infertile then I suspect the infertile among us would have been bred out long ago. So yes, if the infertile were easily recognized as being different we would most likely have the same revulsion.
That was too quick of a response. Obviously you cannot "breed" out infertility.
NM, the point is clear. I think your argumentation is flawed because of the following:
1. If you would observe a given infertile couple in a certain social environment the odds are that many people know of their 'condition', thus making it an identifiable trait. Even if the majority of the others present in the environment in question would totally disaprove of homosexuality, it is totally unrealistic to expect that they will label our guineapig couple as repulsive. The most common reaction is one of sympathy, I think we'll agree on that.
2. Although not for the same reasons, couples childless by choice are in practice just as much a threat to the continuity of the human race as infertile and homosexual couples. I think that we don't have to argue for a second about the predominant lack of disgust you'd find for the first category anywhere.
