Honoring the Constitution
Just as the Founding Fathers didn't apply freedom of religion just to Christians, neither did they limit freedom of speech, freedom of the press or freedom of assembly just to those who behave politely or avoid offense. How could it be otherwise? If freedom of religion means anything, it must apply equally to minority religions. And if freedoms of speech, press and assembly mean anything, they must apply to all — most particularly those whose views might not be in the current mainstream.
In a democracy, if freedom is not available to all, then no one is truly free.
