I also believe that Islamic requirement to convert nonbelievers doesn't include believers like Jews and Christians.
This narrative allows the potential of compromise between religions.
There is no basis in fact for any of your beliefs. Open your eyes. The Koran states that Allah is the great deceiver. The Jews clearly define the great deceiver as Satan. Would the God of Abraham be known as the great deceiver?
Islam worships the God of Abraham as much as the Mormon’s do. Islam is a made-up religion. Mad Mo needed a way to control the people he conquered, so he created the cult and “scriptures”.
I would even say that Jews and Christians don’t worship the same God. I guess as a Christian I could say that Jewish people do worship “my” God - they just have it wrong. But I would guess they would believe I was worshiping a false God, much as Muslims do. Except that Jewish people don’t go hacking people’s heads off or blowing up buildings for worshiping a false God.
