Surely some Jews do have insecurities. Some. It's a matter of an individual basis, just like with every other people. Btw, 'white' doesn't really matter to me as a Jew anyway. It's Jews vs. Goyim, not 'whites' vs. 'non-whites'. White is a term used mainly in the New World anyway, as an identification for people of mixed Euro ethnicity. It's not really a term that anyone from the 'Old World' would even actually relate to. People primarily identify by their ethnicity/nationality here, not by a colour.
