Actually UR, I meant that as well. Feminism was around pre-WW2 and pre-WW1. When one studies the impact on Judaism that all of these Leftwing utopian movments had it is very interesting and saddening. These things have been going on since pre-the 1500's at one time or anther. I think even pre-Plato. All had saddening influence on Jews and Judaism... More specifically closer to our times would be the Bund which was associated with different "Leagues" "League of the Just" etc. and its followers like Rosa Luxemburg, Karl Marx, Max Lillienthal or Abraham Geiger, founder of Deformed "Judiasm" and that rat years later "Rabbi" Sephen Wise... If you read up on these groups like Hellfire Clubs which sprouted up all over England and Europe, or groups like the Rosicruscians, Jacobins, Sabbatains, Domneh and the Frankists all were influenced by these aforementioned ideologies and all played an impact on Jews and Judaism....sadly..
I could go on about this subject as it is one that I've studied due to my education in politics and political movements. It is tragic how this infected Jews and Judiasm.
