When Margaret Doyle’s temper exploded inside the Virginia General Assembly a few weeks ago, a photograph of her being ejected from the state Capitol became a symbol of front-line resistance to legislative assaults on women’s reproductive rights. Doyle, who is 53 and weighs 115 pounds, was so fired up that it took four police officers to restrain her. Other protesters also were subjected to the strong arm of the law.  A debate over the role of religion in political life has shaped recent clashes over contraception and abortion. Curiously to me, nearly all of the women were white.
