Women have been fighting for representation in government, pay equality, education equality. None of those are helped by owning a gun. How many women have had their access to personal development opportunities restricted by their inability to apply deadly force? I'm guessing it's a trivially small number.
It makes it a lot more expensive, shall I say, for the opposing side to rid themselves of such turbulent agitators.
There's memorials to people who were killed during the Civil Rights era; there's not very many names on them, around 33 for the first I heard of, 41 for the SPLC's https://en.wikipedia.org/wiki/Civil_Rights_Memorial and it includes a number that aren't relevant to my point. One reason for this is because a lot of them including Eleanor Roosevelt were armed.
