Actually it's the idea that they are equal that is a "talking point" without a citation.
It's pure ideology: "we should be, and therefore we are", which takes for granted what it ought to prove.
Plus, when we are faced with some thousands of years of history, common worldwide family patterns, and similar observations in nature to that effect, then it's the counter claim that should come with evidence (extraordinary claims need extraordinary evidence, burden of proof, etc).
" and similar observations in nature to that effect"
Which one? Examples without mammals that breast feed their offspring which a male in mammals can't do?
Or did you mean elephants, "The females spend their entire lives in tightly knit family groups made up of mothers, daughters, sisters, and aunts." http://en.wikipedia.org/wiki/Elephant
so we should raise our chilren in tightly knit groups and drive the males away?
Should we throw marriage out because nearly no mammals have long monogamic relationships?
"Plus, when we are faced with some thousands of years of history, common worldwide family patterns, and similar observations in nature to that effect"
Your lack of citations seems to be a modus operandi.
One which resembles our own, duh. The idea is that each group came to develop in a specific way. So, no, a counter-example with some foreign to us animal wont cut it.
>Should we throw marriage out because nearly no mammals have long monogamic relationships?
This is something we developed, culturally, but since you ask, why not? Its not as if we havent already, what with divorce, polygamous arab cultures, adultery et al...
>Your lack of citations seems to be a modus operandi.
Its a forum, not an encyclopaedia article. Do you discuss with citations? If yes, You must be very popular at parties. In an case, the intertubes are one click away. Feel free to investigate what I said
