I do catch your drift but you may be refering to grown children either adopted or in a foster home. What I mean by a child raised in a gay household is;
A baby raised from birth by two same sex parents. I don't think there are many cases of this type of child that are currently of adult age now. I am not one to say let's wait & see what happens with these children. I do not have faith in society when it come to this. I do believe that it could be done right but for every sucess there is the potential for many broken lives.
It's good to have a mature discussion about this.
