No, Michael Moore, we are not all Muslim! We may be more rightly called Americans.
It is a wrong, illogical, and even an unconstitutional conclusion you have come to to assume this American a Muslim.
This American was once a hell bound sinner; but now, by the grace of God, is a born-again, follower of the Lord Jesus Christ, as described by the Holy Bible, not the Qur’an, Book of Mormon, Watchtower, or emotionalism.
No Muslim would say they are Christian and still be a Muslim. Nor do I argue it would be a helpful thing to ask them to do so.
No Christian will join your publicity campaign.
