The only really healthy environment in which to raise a child is in a home with a father (male) and a mother (female) who are married. Ideally, the mother should stay at home to care for the child and the home environment. Anything else is less than optimal. Maybe a child can grow up in another environment without turning into an ax murderer, but the child will be damanged in various ways. Having a bunch of people unrelated by blood running around in a house fucking indiscriminately, coming and going, is not going to provide the needed role models, nor is it going to give stability. Anyone who thinks these freakazoid arrangements are better than a normal, stable nuclear family is kidding himself.
