So once you stamp out the big, easily measured objective forms of oppression, you find yourself on a treadmill where working harder and harder to suppress the little stuff doesn't do any good. Each generation feels that they're as oppressed as the one before, even if objectively things have changed dramatically in their favor. The only way off the treadmill is for the 'victim' group to stop viewing every experience through the lens of imagined oppression.

Do you seriously think that proves we shouldn't try to stop what we asses to be "oppression"? Diminishing returns do not equal zero returns.
