"Thank you for the invitation, Adam, and for your thoughtfulness in extending to me in particular a personal call. But I'm afraid I must decline. While I appreciate that I would be your "brother in Islam" if I became a Muslim and turned my "sword against the enemies" of Allah, I cannot and will not give in to violent intimidation, come what may, and I do not want to live in a society that bows to such intimidation.
I believe that societies that respect the equality of rights before the law of all people, including women and religious minorities, as well as the freedom of conscience, are superior to those that do not. I hope that such societies will be able to summon the will to resist you and your "invitation" in all its implications before it is too late.
Meanwhile, Adam, I have a preliminary invitation of my own for you: I invite you to accept the Bill of Rights, and enter into the brotherhood of Thomas Jefferson and James Madison. My invitation does not focus on my religion, although I invite you to that also, but rather on a framework within which people of differing faiths can live in peace, harmony, and mutual respect -- provided that none of the groups involved cherishes supremacist ambitions to subjugate the others."
