When I see people post stuff like this on Facebook, I want to invite them out for a beer so I can spit in their face. Trying to fight jackassary by suggesting (even sarcastically) other things that people could ban is a whole new type of jackassary.
I don't see it that way.
They're not suggesting something else to ban, because people only want to ban stuff that affect other people.
They are merely pointing out the holes in the arguement.
