Tattooing and cannibalism

I'm reading Walter Rauschenbusch's Christianity and the Social Crisis (1907) for the first time, and my favorite quote thus far is one I'll throw out there for my friends and family members (and perhaps MoJers?) who have tattoos:

Gambling is the vice of the savage.  True civilization ought to outgrow it, as it has outgrown tattooing and cannibalism.

(For a more optimistic view of the tattoo craze, read R.R. Reno's thoughtful essay from last year.)
