I actually have a problem with Amazon selling (some) copies of Mein Kampf as well: Neo-Nazi groups have been caught selling their own editions as a way to raise funds. That, to me, seems like a cut-and-dry example of a Bad Thing.

Like I said to 'ehsankia, it's intent that interests me.

Yeah, I was referring to academic editions, and the fact that you have to contort the analogy proves how stupid the argument you're making is.
