That's the subtitle of an essay by Fr. Thomas D. Williams, recently published on National Review Online. Here's how it begins:
You are unlikely to ever come upon a group called Mohammedans for Polytheism or Environmentalists for Seal Slaughter. A Muslim who espouses a multiplicity of deities has, ipso facto, placed himself outside the Muslim confession. Polytheism is not an Islamic thing. An environmentalist who patronizes anti-ecological activities is not an environmentalist at all, but a subversive. This is because the monikers “Muslim” and “environmentalist” mean something; they carry with them a series of necessary consequences. Certain terms — like “Muslim” and “polytheism” — simply can’t be squared, and combining them is nonsensical.
The recent ecclesiastical backlash to Nancy Pelosi’s unfortunate remarks on Meet the Press should have surprised no one, least of all Speaker Pelosi herself. Her attempts to squeeze abortion rights into Catholic moral teaching were no more credible than trying to pass apartheid off as a legitimate goal of the civil rights movement. The bishops — some seven have weighed in on the matter so far — had no choice but to speak out.
