I'm old enough to remember (and to reap the benefits of) the introduction of the "Pill". So, I was well aware of the very beginnings of modern feminism. Let me arbitrarily set that year as 1963 with the publication of Betty Friedan's The Feminine Mystique.
I recall that the feminists of the day made a range of arguments for women's liberation. If memory serves (and it often doesn't) the ultimate rationale for women's liberation was the attainment of a better world for all. If women, the meme went, were equally and fairly represented in all aspects of the community, in law, medicine, government, business, science, education--the list goes on--the world would be a better place for both men and women. Women would temper the "winner take all / survival of the fittest / law of the jungle / patriarchal" ethos of men with their nurturing, compassion, and cooperation.
As grandfather, husband, father, and brother of women, I wholeheartedly, without reservation, and with enthusiam support the principle of gender equality. However, having said that, it seems to me that feminism has never delivered on its promise for a better world and, in fact, cannot. Now rather than simply having male assholes running everything we have male and female assholes running everything.
If we are to be true to the notion of gender equality and women's liberation, we have to accept that women have as much right to be dickheads as men, and they have embraced that right with enthusiasm.
For women, gender equality and liberation has benefited many, and that's good, but it has not created a better world. The promise of feminism hasn't been kept, and it never will be.
