Actually, I thought it was pretty common knowledge. It is not a common practice in the US though. The fact that obama’s father was polygamous seems to be a non-story as well.
It is “common knowledge” that should be roundly condemned every chance that Muslims are discussed. Nothing but poverty, familial abuse, pederasty, abandoned boys and hatred of others can result with polygamy... even when so called “Christians” practice it, i.e. the F.L.D.S.
It is a signal of submission to Islam that we do not rail against polygamy in our campuses and churches. It is not just dysfunctional, it is a guarantee of generational genetic degradation, poverty and environmental disaster due to overpopulation. It is a fundamental difference between them and us, and it explains a lot.
