1)Two gay men is not a father figure. A father figure is the run of the mill "lets go play a game of catch and talk about girls". I am not saying that two gay are any less of a father, but it is not the norm.
2)I picked roman as an example, I could pick at on of historical sources to show flaws in children of single parents. this is to show its nothing new, evne if times change.
3)I never said society was pretty. Infact I said life is hard. However, in most every single society (I cant think of an Angellical society where this wouldnt take place) you will rub elbows with someone who will not approve of your parents, and you will feel the impact in one way or another.
4)Im not saying adoption isnt for everyone, i feel as though homosexual couples, despite how "ready" they are will NEVER be the best choice for the CHILD. The couple obviously must be positive they are ready, but I assume thats given most of the time.
To answer your question, Id say the question should be Adoption vs Orphanages. Even then, I do not know enough about the latter to make a fair claim. Sorry for the dis-oranged numbering of responses, I am exhausted
