I've associated feminism with "women make $0.67 for every dollar that a man makes for the same job, working the same hours" and equal gender ratio over equal opportunity.
Based on numerous conversations I've had with self-identifying feminists, I would say the primary message seems to be that a person's gender (regardless of what it is) shouldn't decide their opportunities in life. Opinions on the extent or existence of systemic societal discrimination against women tend to depend largely on individual experience
(and admittedly, on occasion, misinterpreted and badly gathered statistics) I think. And of course, there are as many versions of feminism as there are feminists because no two people are exactly alike.
