I still don't understand what you think the bad side is, and the lack of a presence of a mother is not a good one. By your reasoning, a lesbian couple would raise their children twice as good.
Your pedophiles statement does not make sense, especially with the use of "under-age boys" to support your claim. As if pedophiles don't approach under-age girls.
The widower point I was trying to make is that that man, without the presence of his wife and the child without the presence of his mother, can still raise a child under the correct guidance, because children do not need a female presence as a parent, but rather surrounded by people who love them unconditionally with proper guidance.
