To resist the laws many of the Jewish people would find loopholes in the laws. For example, in the law prohibiting marriage between Jews and Germans or related blood, it doesn't describe who or what a Jew is considered. Because of the past several years of Jewish and German assimilation, it was really difficult for the true specification of a Jew for several months after the law had been released (Jason Levine).
Also to resist the laws the Jews established the "National Representation of German Jews.(Reichsvertretung der Deutschen Juden)" This was an organization created by Jews to respond to the growing prejudice towards the Jews. The Reichsvertretung was mainly formed to provide education and establish Jewish schools, guide Jewish youth towards vocational training, strengthen the religious base of Judaism, protect Jews' economic status and right to work, and prepare-especially the youth- for building a new life in other places.
