Phil Johnson gives five reasons he’s not jumping on the anti-Slice bandwagon here:
Pyromaniacs: Slice Capades

I’ve struggled with this question myself recently, since I, too, link to Slice of Laodicea from my “blogroll” on the right. But I have to agree with Phil:

Most of the abominations highlighted at Slice really deserve a healthy dose of righteous indignation. Personally, I’m embarrassed that evangelical outrage is so easily mustered against the “tone” and “tenor” of a Slice post decrying youth ministry modeled after a circus sideshow while so few are outraged by the common practice of making a burlesque of evangelistic ministry.

While the “tone” and “tenor” at Slice can sometimes be harsh, I agree that the outrage is too often very misdirected… Like the psalmist, we should be indignant at the forsaking of God’s law, not at those who point out error.
