@engineer,
I think this article makes a difficult argument...
Let's say Carrie Nation went wielding an axe to fight the evils of abortion (rather than the evils of drinking). This is not difficult to imagine, there are lots of Christian women who are willing to break laws and even commit violence to stop abortion.
The article is arguing that this is justified because...
1) She had a sisterhood (the pro-life movement has a similar sisterhood).
2) She helped downtrodden people (which fundamentalist activists often do).
She was a religious extremist with a mission. I think trying to turn her into a feminist icon is an awfully big stretch. The temperance movement she pushed was a historical failure, and progressives are now pushing in the opposite direction to legalize marijuana.
Carrie Nation has far more in common with Phyllis Schlafly then she does with Gloria Steinem. She would feel comfortable with the strong conservative women who fought against abortion and pornography.
