Ah, the free speech and morals debate.
Example one, I don't see anyone sending about petitions for the freedom to kill people, simply cause its morally wrong; (for most people).
Now you have to draw a line were stuff we see/hear is morally wrong, as a government that are elected. They do that to what they see fit.
People seem to think that the government can get away with it all, but with the power of the media in many developed countries, (sorry, not too hot on others); the government are restricted to what they can show simply because they would be ridiculed otherwise.
Sometimes I think the media influences government decisions too much and this maybe is its fight-back.
My two pence.
