Just to be clear, I see polygamy as bad only because of the women oppression aspect. But the world is a big place and history is long, so I wouldn’t be surprised if at some point there was some system that allowed for polygamy without oppressing women. Mentioning mormons - don’t you think they can be seen as another weird different group - and therefore be also object of xenophobia? Notice I intentionally didn’t use the word racism, what I mean is just the sentiment that people doing things differently than my group must be deadly wrong.
