The Quakers were perfectly capable of innovative thought, and of thinking through the consequences of their principles (thus relative sexual equality, concern for animal welfare, and encouragement of vegetarianism); but they were fine with using brutal violence against anyone who didn't accept their doctrine of nonviolence -- especially those from different cultures, and followers of different religions (or different Protestant denominations; they were particularly cruel towards the Presbyterian Scotch-Irish). This is why they get under my skin.
