If I were to compare the effect of religion on the health, wealth and happiness of humankind with the effect of, say, feminism, I suspect feminism would win easily. Feminism has never airbrushed men out of the picture — either literally or metaphorically. It has never raised an army, never armed itself and never passed laws restricting the equal rights or opportunities of others. There may have been terrorists who were also feminists — in the IRA or the Baader-Meinhof gang, for example — just as there have been terrorists who were also atheists, but there have been no feminist acts of terror.
Feminism has never killed an opponent. Feminists have died, of course, usually at the hands of the religious. The suffragettes certainly smashed a lot of windows and even set a few fires (always in buildings they knew to be empty), but they never actually hurt anyone other than themselves. Suffragette Emily Davison was killed throwing herself under the hooves of the King’s racehorse at the Epsom Derby, crying “Votes for Women!”, and many of her colleagues went on hunger strikes when jailed for their beliefs, and then suffered the indignity and torture of force-feeding.
