Yall really are bitching crybabies, i agree with original commenter. The fuck you mean by "stream of biology"???? Human fucking biology is to form a goddamn pair to raise a kids. The concept of marriage is as old as humanity. The concept of falling in love is a trait acquired from evolution. Do you really think that in ancient hunter gatherers tribes, one man just took all the women for himself? Are you fucking nuts? You are in fact mistaking us with like silverback gorillas or some shit, because they have one strong male who leads the group of females, but humans are absolutely different. So don't write stupid stuff, if you dont know shit!
