My kid will not have parents that fit in, This would be true even if KellyM were not in the picture. My child will be born of an obese bisexual feminist married to a somewhat fruity, pastel wearing, teddy bear collecting, obese, disabled man. Children do not have the right to have parents who are perfectly normal. Odd people have as much right to reproduce as anyone else. Children deserve the love and support of their parents, but not parents that fit any specific mold.
I know scads of children with 3 or more parents. I know many who have made parental bonds with step parents while maintaining the bond with their original parents.
What consenting adults do in their own homes leads to raising children. What people do in their own homes is called family life. My family will have 3 parents and 1 child starting next spring.
