Yes, that's fair reason.
For me, I don't think that I will raise the kids, regardless on marriage, opposite sex or same sex. There are some married couple have no kids, however one member - diehardbiker told me - I never know that I may have kid or not because he had same hope about never have kids in past, but now, he has 2 kids.
Back in more than 50 years, I think you may remember that, the poor families used to had a lot of kids, like my father had 6 brothers (3 died due to health and car accident) and my grandfather had 10 siblings (many are died due to health, car accident, suicided, murdered), they were from poor families. Today, the welfare of children are much better than previous generations.
I was anxious about some members may paint gay parents as bad taste, but I'm glad that you have fair reason.
