Joseph – you didn’t read my post clearly enough – I said “Unless you’re living in a patriarchal society” i.e. like a Muslim society. With the exception of Iran, how many Jews live in muslim countries anymore? Probably a few dozen in each (I remember over a decade ago hearing a news report there were only like 8 Jews left in Baghdad) I’m talking recognizable Jews – not halachik Jews living as muslims such as girls kidnapped and forced into muslim marriages or descendants of such cases. I could be mistaken – maybe there are kehilot in places like Tunisia or Morocco still but even in those cases is it even more than 100 people?
Anyway back to my original point – unless you are still in a country like that which virtually no Jews live since a generation ago, polygamous marriages just aren’t shyach.
Even in societies were it was acceptable and practiced among yiddin do you have proof that any such marriages were actually successful? The Gemara itself says that ideally a person shouldn’t marry more than one wife. If you want to be a smart alec that’s fine but if we’re being honest it’s an idea that would never work in real life and in 90 percent of cases lead to shalom bayit nightmares.
Joseph are you married? If so just ask Rebbetzin Joseph how she would feel if you took on another wife. Then come back to us and tell us how good an idea it is.
