Evolution (and therefore cultural evolution) generates patterns for a reason. Traditional monogamous pairs in a nuclear family are best at producing offspring that are stable and successful enough to produce more offspring. The other behavioral patterns die out when there is no one to perform them.

(I say this as the child-product of the sex-and-drugs 70s, who has no intention of producing his own children.)

It seems like the only successful alternative to the nuclear family is the Islamic model of single husband, multiple wives - one successful man producing a ton of children. At least there are rules in place that the wives are meant to be treated fairly and equally. Whatever the downsides for womens' liberty, Islam is spreading steadily across Europe, so from a reproductive standpoint it works.

I'm not advocating for any one system, and it's certainly exciting (and sexy) to break the rules. But there's no surprise it's going to be emotionally fraught and potentially destructive to do so. But as you say in your logo, it can be quite fun to be a monster, after all.
