>EBay specifically bans their sale while Amazon bans the sale of "products that promote or glorify hatred, violence, racial, sexual or religious intolerance or promote organizations with such views."

Seems to me they both [generally] ban Nazi merchandise but have problems enforcing the ban.

Anyways, its irrelevant. Amazon can sell what it wants. That's a business choice they make. I don't care what they choose to sell, that is their choice.
