re: Thank you for the explanation
I think that your view point is that because "others" are bad we must follow their example?
I agree that because "others" behave badly and do not obey the rules, "we" must defend ourselves.
But, because we are forced to defend ourselves we digress to the same moral level as the people that do not obey the rules.
I wonder if there ever will be a time that such vicious circle of immoral behavior, breeding immoral behavior, will be just a memory.
