You are viewing this wrong because it isn't about tastelessness. It is about infringing on the rights of others. Publishing the Mohammed comic isn't infringing on anyone's rights (at least in the US with our strong freedom of speech and lack of federal blasphemy laws.) However you have a right to not be unknowingly filmed while having sex and have that video published. In the comic example you might be offending someone's sensibilities but that isn't enough to violate their rights like the sex tape example.

Or let's use a different example like the Stanford rape case. No one is reporting the name of the victim of that case, but her name is a "raw fact" of the case. Would you support releasing her name and if not, how is that different that releasing the sex tape?
