Now, unless I missed it somewhere, here is an important point that no one seems to have considered: a pretty large number of children are accidents. It isn't necessarily that they are not wanted, but all too frequently they are not wanted now. And sometimes they are not wanted at all, and there are occasions where the resulting resentment by one or more of the parents leads to child and/or spousal abuse. Not a nice atmosphere to grow up in.

When a gay or lesbian couple adopt a child, it's not an accident. You can be sure that the child will grow up in a home where he or she is wanted.

P. S.:   Now, I'm quite sure that there is someone around who will try to do a raunchy play on the word "wanted," but that, I think, is that person's idea, not the idea or intent of the gay or Lesbian couple.
