Jewish or Jew or Judaism

I find it kind of interesting that orthodox Jews who consider themselves Jewish and practice a strict for of Judaism never use these three words. You would think that orthodox Jewish folks would be more keep on using the term Judaism to describe their beliefs, after all we are constantly asking ourselves whether or not we are American Jews or Jewish Americans. Just wanted to share my little mind and toungue twister thoughts on being a Jewish Jew that practices Judais.

PS – why isn’t it called Jewdaism?
