"Do not open your mouth to tell me that your mind has convinced you of your right to force my mind. Force and mind are opposites: morality ends where the gun begins. When you declare that men are irrational animals and propose to treat them as such, you define thereby your own character and can no longer claim the sanction of reason--as no advocates of contradictions can claim it. There can be no "right" to destroy the source of rights, the only means of judging right and wrong: the mind."
-- Ayn Rand, Galt's Speech, Atlas Shrugged
Of course when I advocate literally returning fire at the practitioners of force I get called all sorts of names, like "the embodiment of all evil on Earth."
