Most of Hollywood espouses serial polygamy, with or without any religious or civil ceremony. It essentially mirrors the Muslim practice of “temporary wives”.
American popular culture is guilty of extreme hypocrisy when it vigorously condemns Muslim, “Mormon” or African tribal polygamy yet the majority of our entertainment features this serial polygamy or the “temporary” polygamy of adulterous “affairs”.
Not many TV shows or movies feature a one husband, one wife, never divorced, faithful marriage these days. The preponderance are about divorced people or singles “hooking up” or some married person having a torrid extramarital affair.
Our "pop culture" does not condemn those things. Our real culture does, mostly. The entertainment industry bears zero resemblance to at least half the country.
It should be noted this practice is largely, though not entirely, limited to Shia Islam. Quite rare among Sunnis, at least in formal terms with a preset date of termination of the marriage.
BTW, what up with this stuff about polygamy being "rare" among Jews?
