Suppose I go to DU and say something you don't approve of. Say, oh, 'Barack Obama's wife looks far more like a monkey than does George Bush.'
I get banned from your site, no?
Say, how is that banning represented, now that you're all outraged about crosshairs on a map?
Yup: a TOMBSTONE. Implying DEATH TO THOSE WHO DARE DISAGREE.
Any questions?
