But in the last option, their sexual orientation isn't a factor at all anyway.
"No, unless a heterosexual couple is better qualified in ways not related to sexual orientation"
Adoption should go to the most qualified parents. The fact that they may be homosexual or heterosexual is irrelevant.
That's what the last option means and that's I voted for.
The other option says "No, they should never be denied".
There are no if's, and, or but's in that equation.
Is that option supposed to be some sort of "Affirmative action" like idea for homosexuals that you're giving it to a particular homosexual couple that has already been determined to be less qualified in areas not related to sexual orientation?
I took the third option to mean that couples are either qualified or not (i.e. there is no better or worse qualified, merely qualified or unqualified) and therefore children should be doled out on a first-come basis to any qualified couple, same sex or otherwise, without trying to determine who is or isn't best for the child. That matches the second option, which implies a minimum qualification for regular (hetero) couples such that, as long as any hetero couples meet the minimum, gay couples would automatically be disqualified, while still allowing gay couples to adopt if no hetero couples meeting the bare minimum were to be found. Therefore your choices would be:
(1) Never!
(2) Maybe, but only if the supply of hetero couples meeting the bare minimum is exhausted.
(3) Yes, as long as gay couples meet the bare minimum they should be allotted children on a first-come, first-served basis, without regards to sexual orientation.
(4) Yes, but the best qualified couple (considering everything relevant) should get preference in adoption.
But since twenty people chose the third option, I suspect most people took it as merely a knee-jerk reaction about whether sexuality should be considered at all, in spite of the wording of the last option. You could come up with a lot of difference permutations - for instance, I'd rate a lesbian couple higher than a gay couple and lower than a hetero couple for raising a prepubescent girl because I think a lesbian could answer "dad questions" better than a gay man could answer "girl plumbing questions". But in the end you could easily come up with more permutations than respondents. There's also probably a great tendency to overweight such factors if they are considered at all. In the case of a single dad raising a girl child, unless he's independently wealthy he probably thinks finding enough time and energy to raise the child is a more daunting problem than answering the "mom questions" or "girl plumbing questions." Single parents make do, therefore gay parents would do the same, and two parents in a stable, loving home beats one. Especially if the child has already lost one set of parents, start him/her out with a backup!
