Hell, /r/chapotraphouse was banned for allowing members to call for the death of 19th century slave owners. Sitewide rule enforcement on R*ddit is pretty arbitrary and at the convenience of the admins.
That's not why chapotraphouse was banned. You can still find tons of links on shitredditsays pointing out members of that sub calling for the death of still-living people, or entire races of people. For example, see the not-very-subtly coded references to baseball, referring to the assassination of Scalise.
