I respect your opinion. I respect the opinion of Rush, et al more. Their opinions & decisions aren’t rooted in religious bigotry. I feel pretty confident they know more than you. But to each his own.
Based upon his religious litmus test, AMPU would have refused to vote for many of the founding fathers (including John Adams and Thomas Jefferson) who, according to AMPU’s religious litmus test, weren't Christians, but instead were heretics because of their nonbelief in the trinity.
John Adams, a Unitarian, who rejected the trinity responded to the religious zealots of his day as follows: Howl, snarl, bite, Ye Calvinistick! Ye Athanasian Divines, if you will. Ye will say, I am no Christian: I say ye are no Christians: and there the account is balanced. Yet I believe all the honest men among you, are Christians in my sense of the word.”
It is sadly pathetic that John Adams had to have his faith disparaged by the religious zealots of his day and, if possible, such religious zealots would have denied him the office of President. It is equally sad and pathetic that even though our nation was founded upon the principles of religious freedom and tolerance, we, as a nation, are still dealing with the same religious zealots, isn't it?
