the usual idiocy ...

... I also recall a group of former fundamentalist Mormon wives who had left abusive, plural marriages, and now advocated against ALL plural marriages, never pausing for one second to note that both men and women are sometimes abused in monogamous marriages, in non-marital relationships, in brief encounters, or even by strangers.

It's the abuse that is the problem, not the circumstances in which it occurred. Unfortunately, when the circumstances are uncommon the people who were abused in those circumstances tend to want to blame the circumstances rather the specific persons or problems involved.
