According to Genesis 18 verse 1-8: as an act of covenant with God all the men, including Abraham, in his household were circumcised. It is a mitvah one of 613 commandments that Jews follow, some to a lesser degree - many Jews are not orthodox, many barely go to the synagogue, some may barely believe BUT all their boys are circumcised. So a law in Germany, or anywhere else will be ignored. As there aren't that many Jews in Germany [I wonder why], it will be easy for them to slip over the border. It may even force the ones left to leave. Why anyone would want to stay in a country that systematically tried to eradicate your race is beyond me. So it just makes this whole ban ridiculous - when it comes down to religion people will stay fast to their beliefs. It will not stop the practice . Female circumsicion is not in the Bible or the Koran it is not done out of belief but custom.
