So you ban this extreme sort of thing, and you're happy. For a while everything's good, and Daily Mail readers such as yourself the nation over rejoice.
Time passes and after a while stuff on the scale of Saw and Hostel starts to look distinctly tasteless. With anything more severe being banned, these are now the most severe thing about, and surely, if Grotesque deserved the banhammer, why don't these?
Time passes and with no Saws or Hostels about, the violence portrayed in Tarantino films starts to look distinctly hardcore.
In the end you're left with Bambi, but even that gets censored as the murder scene is far too graphic.
Slippery slopes!
