I don't think that the comparison to handicapped children really works.
The reason is - if no-one in the world had a problem with gay people, if religious fundamentalists did not preach against them, if gay people were not attacked door being gay, and if gay teenagers didn't feel like freaks of nature (because of the attitudes of others), then being gay would be no more of an issue than being left handed.
All the issues that gay people face are external. This is not true of handicapped children, who would have difficulties even without any external locus of discrimination.
This is not the fault of parents. I can say with some certainty, that in the past people would have been upset at the prospect of having a gay son or daughter, because they knew how hard life would be for them.
As we trundle into the future, that will be less and less of an issue. I strongly suspect that we now have a generation of parents who wouldn't care if one of their kids were gay, as long as they had another to provide them with grandkids.
And as every woman knows, having a gay son is a major advantage as they grow older, because gay men know how to keep their mothers away from chiffon and backlighting.
