The Christopher West of Protestants appears to be Mark Driscoll, who likewise is obsessed with sex and who likewise sees the beautiful Song of Songs as the sex-drenched "centerfold" of the Bible. See a disturbing article on Driscoll here, entitled The Church of Sex. Be advised: Driscoll is not as coy as West, and uses language and examples that are more graphic and "adult" in content.
A friend emails that it appears "the errors of West have spilled all over Protestant-land". I would say rather that this is a symptom of a broader problem in contemporary culture, described by David Kupelian in the linked article:
No matter what kind of person you are, a form of Christianity has evolved just for you. There’s a politically liberal Christianity and a politically conservative Christianity. There’s an acutely activist Christianity and an utterly apolitical Christianity, a Christianity that holds up a high standard of ethical behavior and service, and a Christianity for which both personal ethics and good works are irrelevant. There’s a raucous, intensely emotional Christianity drenched in high-voltage music, and there’s a quiet, contemplative Christianity. There’s a loving Christianity and a hateful, racist Christianity, a Christianity that honors Jews as God’s chosen people and a Christianity that maligns Jews as Satan’s children.
