@Riddler:
"Common decency" is more typified by general community assessment rather than being a personal subjective opinion.
A case in point:
Frequently, arguments about not censoring certain material are qualified with "as long as it's between consenting adults," but what if some users are sexually excited by non-consensual material such as pedophilia, bestiality, snuff, blood sport and torture? Isn't this qualification of consent an infringement on censoring personal interests and therefore should be considered invalid? I mean we could simply have these things labelled, right? And allow others to chose to watch or not. . .
Certainly this does not involve an issue of legality. If we relied on the legal precedent of protecting the rights of others in a non-consensual manner, torrents of IV drug use could be dismissed because of a near universal illegality of intravenously consumed substances. So if not legally based, where is this qualification against non-consensual activities coming from if not from some collective assessment of "common decency"?
How is this non-consensual principle a justifying concept with the anti-censorship folks if it violates, at the same time, some users' personal interests, the predominant issue of anti-censorship?
Almost sounds like the slippery slope argument. If we allow this item then we will have to allow these items as well.
I don't think it is an issue of "consent" but more of one of morality. Pedophilia (which btw is not illegal), bestiality and snuff all have moral issues attached.
