If you can prove that statement then it certainly deserves to get shutdown, but you cant
if you read something in the newspaper and it makes you angry and/or sparks an extreme reaction, should that newspaper be banned? or a TV network, or any other news source?
Its a slippery slope if you go down this road IMO
Too many non-lawyers on this board think that saying "slippery slope" makes two things on the opposite ends of the spectrum one and the same, and that's not true at all. The law is perfectly capable of handling degees of difference. After all, there are no less than 5 degrees of homicide (more, depending on jurisdiction).
It's quite possible to ban a newspaper that says "Kill all the X this weekend" without it having any bearing on a newspaper that opines "X people should die." If you can't see the difference between the two, then I won't bother responding further.
