I can answer your question about how people find the Masons Anti - Christian.
It is simple. Christians believe that God is the Truth and the Light. The only way to salvation. That His Word is the truth.
The Masons freely accept other faiths. That in and of itself is against the teachings of the Bible.
Christians don’t need to believe in conspiracy theories to disagree with the basic Mason structure. The Masons themselves reveal enough for us to know.
Can you be an AMERICAN and be a CHRISTIAN?
Sorry, your logic on this matter is weak.
