"Islamic history is about putting people to the sword if they do not accept the religion"

Ted I totally get where you are coming from but you are talking about "Haddith-Islam" that exists in 99.9% of the world, which is based on reading the Qu'ran through the Haddith. I am talking about "Messianic-Islam", which is based on reading the Qu'ran through the Bible. 

It is arguable that "Haddith-Islam" took over very soon after the death of Muhammed. The Sunni-Shi'ite split happened almost immediately after his death. 

It is not unlike how "Catholic-Christianity" took over very soon after the death of the original apostles. We Adventists "disown" the atrocities of most Christian history too, by saying they were "apostate" Christians. 

I personally believe Muhammed WAS a false prophet. But many Christians also claim Ellen White a false prophet, with a later "book" too and Adventists are not "Christians". Yet these are not "salvation issues" if someone accepts Christ as their saviour.
