>I just said the opposite. I can imagine many people genuinely caring for a child that isn’t their own.

Sure, but limited to "family and friends". Following that up with "who does not know my children" indicates you clearly view empathy as extending to merely one's personal relationships and you seemingly can't imagine caring for a stranger's child. I'll grant you cyncism is not the correct description of that worldview, but I stick by the general label of disturbing.
