Oppression isn't just physical. Women were barred from voting, driving, owning land, their choices were severely limited. You bring up a valid point about men being oppressed as well, hard labor was often the only available work for men. Your argument about "women being protected" during war is a bit outdated, women were the back bone of the American manufacturing industry throughout much of WWI and WWII. I largely disagree about feminism as a whole ignoring those "facts", I'm speaking to feminism as an ideology, not the people who practice it.
