Godwins “law” is a meaningless silliness, that is often the last refuge of a smart-ass. Why is it weird that one of the worst insanities within living memory might sometimes be referenced when people discuss politics or pphilosophy? I could easily make my own “law”, whereby any discussion about the roots of nazism, or even the most scholarly legitimate comparisons will soon invoke a shriek “Godwins Law”.
This law is not an axiom of logic, it is just someones crotchety attempt to prevent anything, from ever, for any reason being contrasted with the nazis. (one of the most nightmarish developments of the last century) These comparisons are very often quite legitimate.
I often think if i suggested we follow nordic pagan religion, blame the Jews for everything and ship them by trains to special camps, and someone compared me to a nazi, that someone could be counted on to shriek that Godwins Law was invoked.
