Everything you say about Mohammed and Muslims you can say about Christians. Remember the crusades? The dark age? They preached what you preach...
Yes, but the different is that Jesus taught love your enemys. And not all Christians which believe they are, are Christians. 25 years i believed I am a Christian, because I was baptised as child. Then Jesus revealed me, that I am not a Christian, without him. The mayority of Christians in germany are name or nominal Christians, as I was.
So we must maby distinct between Followers of Jesus Christ and nominal Christians.
Btw Without Mohammed no Islam, without Islam no Crusade to free Jerusalem. But this is another Box.
Clear is that the God who reveals himself in the bible and Mohammeds God have nothing common.
And you cant explain this fact away. The Islam denyes that Jesus is Gods son!
