It's not the question that's wrong, but what you do with the answer that's important.

It's like asking - is it true that black people have statistically larger lips than people of other colours - then is that really racist? I don't think it is. But if you take the answer to that question,and somehow infer from it that because of it your "race" is better than others, then it only means that you are racist,not the question.

My point is - scientists need different kind of statistics to understand how the world works. If they ask if a child raised by two gay people is more likely to have problems with its own sexuality, then I don't see that as homophobic or aggressive - it's not personal after all.
