With all due respect, don’t post Wikipedia as fact or unbiased.
I would say the best that this categorization does is that it acknowledges Jews as an ethnicity for those who do not recognize it already; however, the dichotomy between Jews the people and Judaism the religion is not expounded upon here. (Marx may have been a Jew by ethnicity, but he was a hardcore atheist.)
