you might be right about adoption agencies, NJ , in particular about the anti-cigar one - they aren't necessarily all as bad, but friends of mine did have appalling trouble trying to adopt, mostly because of council incompetence.
But it doesn't follow that those who raise children have to be male and female; I don't think "what is available naturally" need be our guide to life. It would rule out trains, charities and suntan lotion - and yet, manmade though they are, all these improve our lives.
