I am not being glib, I simply don't know how else to respond to "why not allow games about raping people, or paedophilia, or abusing people in a romantic context" other than with "because all of those things are objectively unconscionable." And, yes, I'd argue that they are all worse than Video Game Violence™ even when just taken within the "it's just vidya" context.

I dunno, I fully accept that it may be just getting old and outdated, but... I genuinely can't see that stuff otherwise, nor could I agree with the distribution of such stuff out of the same website on which you can also get, like, Tiny Tots' Fluffy Fun Town Adventure, the hit platformer for 1-year-olds, y'know?

I'm not stupid enough to believe that such stuff will never exist, as I've seen it exist already. Like, ok, but that's different. Horrid stuff will exist in one way or another, there's still a market for snuff films and such, ok I can accept that as an inevitability. But it's one thing for It to exist, and another to sell It as one would a can of soda, in full view and reach of just anyone.
