The contradictions of the left regarding radical Islam are about the equivalent of, say, the NAACP coming out to support the Klan.
Not really. What the radical left really hates is the Gospel, as the Christian understanding of Man is the primary impediment to the establishment of an omnicompetent State. Islam is simply another route to the omnicompetent State: Sharia regulates everything in everyone’s lives down to a nicety, the same way the left wants to.
If you want to analogize Islam to the Klan, the radical left would be more like Stormfront than the NAACP in such an analogy.
