Back in the 20th century (lets say 80 years ago), pro-Nazi (not “neo-Nazi”, real honest to goodness pro-Hitler “National Socialists”) political groups were reputable, popular and drew broad support. Many American leaders openly supported anti-Semitism. The major universities had restrictive quotas on Jews (today the only quotas are on Asians, plus affirmative action quotas for Blacks that are too small to affect us, since the “white” quota is very liberal). Jews, even secular assimilated Jews, had serious concerns about their safety and security. Orthodox Jews were generally excluded from employment outside the Jewish community, since the standard work week was six days a week, and no one heard of flexible work schedules. And had a few battles gone the other way (e.g Britain surrenders under terms similar to the Germans) there would have been a serious threat of Nazis winning the war.
Today: a Jew can walk around in public anywhere in the country without fear of being attacked because they are a Jew. We can go to any university and enter almost any profession. Shomer Shabbos Jews have held high public office. Open expressions of anti-Semitism are roundly denounced by all political parties, even the Democrats who have a small anti-Semitic wing.
We have forgotten what it is like to be a marginal community, right-less, living on suffrance – Baruch ha-Shem.
