What people are pissed at is a card payment network abused for moral regulation.
I'm trying to find a good analogy. Perhaps if someone in your town built a giant meat grinder in their backyard, and as a test run they requested the vilest and most heinous criminals to be sent to them, you'd still see a private entity getting to grind the people they want as a serious issue.
Not wanting to spend a second on that issue, just because of who got sent there, would be quite a position.

Are you suggesting that playing a game involving incest is somehow unacceptable, while a game with graphic murder is fine? It's a strange moral line to draw, and despite what you may think, your views are not shared by everyone.
