What if anything should democratic polities do with respect to political forces and citizens who oppose democratic practices? One strategy is toleration, understood as non-interference. A second approach is repression, aimed at marginalizing or breaking up non-democratic political forces. I argue for a third approach: democratic states and citizens should respond to non-democratic political forces and ideas mainly through efforts at political incorporation. This strategy can protect democratic practices while respecting citizens' rights; its prospects are enhanced by the diverse political composition of most contemporary anti-democratic projects and the integrative effects of democratic procedures.
