By saying "you can't say x and then go on to say y" I'm not forbidding anything - I'm saying it's not a consistent argument, that's all I'm not making any assumptions about you at all, so no need to put words in my mouth. I'm simply reading what you are writing But let's just say the world changes and people are allowed, without penalty, to dispense justice. Can you not see the trouble that would bring and how it would be much worse than the system we have now (for all it's faults)?
