Please post something that expresses a full thought. It is often extremely difficult to understand what you are talking about.
I don't know if this is laziness on your part or if you are just trying to avoid committing to any ideas.
Are you trying to say that in the vast majority of mammals, males catch the food, and females raise children and that because this is true of so many mammals, humans must also behave like those mammals?
If that is your argument, it is ridiculous. Which mammals use language? Hardly any, if any! Does this commit us to giving up language for purposes of communication? Answer: No!
Which mammals wear clothes? Apart from those dogs that are dressed up by humans to look like Sherlock Holmes? Answer: None! So what?
Which mammals cook their food? Which mammals have built space rockets? Which mammals can write? Which mammals play sports? Which mammals have orchestras? Which mammals discuss gender roles on internet forums?
Or do you want to go full Jordan Peterson and start waffling about lobsters next?
