There is no "subset" of Christians who believe the way I do about pagan religions. All real Christians, whether Protestant, Catholic, Orthodox, Evangelical, Coptic, etc, believe that Jehovah of the Judeo-Christian bible is the one and only eternal God who exists or has ever existed, and that His Son Jesus Christ is the only gateway to salvation and eternal life. If a so-called "Christian" actually believes otherwise, he or she can not be a real Christian. All other religions are the work of Satan designed to deceive men and women and keep them from biblical truth and faith in Jesus Christ, and no true Christian can have any respect for Satan or his many false religions.
But we Christians sorrowfully recognize that those pagan religions exist in the US, and that their adherents have the same Constitutionally protected right to worship their false "gods" that we Christians have to worship the one true God. But we can't respect their false religion or their false god(s), even though we respect and pity the deceived men and women who have been duped by the enemy of their eternal souls, and who are under condemnation by God unless they repent of their idolatry and accept the truth of the Gospel of Christ.
Then you should sorrowfully recognize that these poor, decieved souls are as American as you are, possessing the same rights, as invested in this country and its government as you are.
However to refuse to acknowledge that other people can have their own path to salvation and have a happy productive life following their religious beliefs is total bigotry. What ever happened to live and let live. You can try and influence other people to your way of thinking but trashing everyone else as a lesser human being is not what God intends for you to do.
