Godwin's law just means that the longer an internet 'discussion' continues, the more likely it is that someone will compare someone to the Nazis. It doesn't seem to have much to do with mentioning the Nazis in the context of an attempt to ban circumcision in Germany. Besides, the odd thing to do in that context is to not to make at least a vague reference to Nazism.
A connection that is merely cirumstancial (pun intended
), since a local judge in France, Netherlands or some other country could have "banned" circumcision just as easily in an effort to "stick it to the Muzlims".
And if I were to make a prediction, it won't be the last time that Jews end up as collateral damage of Islamophobia in Europe.
