I never will, by any word or act, bow to the shrine of intolerance, or admit a right of enquiry into the religious opinions of others. on the contrary we are bound, you, I, & every one, to make common cause, even with error itself, to maintain the common right of freedom of conscience. we ought with one heart and one hand to hew down the daring and dangerous efforts of those who would seduce the public opinion to substitute itself into that tyranny over religious faith which the laws have so justly abdicated.

Thomas Jefferson (1743-1826) American political philosopher, polymath, statesman, US President (1801-09)
