Well, the thing is that, "according to godwin's law", the probability of comparison grows, and by tradition the person who does make the comparison of a certain action in their daily life to the nazi's, hitler, etc, loses the debate.
The tendency is (unfortunately) that whoever mentions the nazi's, hitler, enz, has allready lost the discussion. That cannot be anything but wrong, because if history cannot be told, there is nothing to be learned from the mistakes that were made.
