The truth is sometimes so simple . . .

. . . so very simple . . .

. . . that even I get it:

[Michel Houellebecq] doesn't distinguish between political Islam and Islam in general. "There's no difference," he said. "Islam is political because it describes the way in which society should be organized." (Rachel Donadio, "Michel Houellebecq, Casually Provocative," NYT, October 12, 2015)

Houellebecq's refusal to "distinguish between political Islam and Islam in general" is precisely why I distinguish between Islamism and Islam in general.
