Not similar to racial purity I m having difficulty seeing the dissimilarity between those who don t like miscegenation because they are worried about Aryans becoming Jewish and those who don t like miscegeneation because they are worried about Jews becoming goyim Whatever the rights and wrongs of the views they certainly do seem very similar If you are arguing that in one case the distinction is racial and in the other ethnic okay that s reasonable but you should note that racial and ethnic are distinctions based on the POVs in question rather than something neutral that simply attaches to the distinction
