Obama, Islam and Christianity

In reviewing YouTube videos on President Obama's take on Islam and Christianity since his apology tour to the Middle East in 2009, it was interesting to hear our great leader praise Islam as a religion of peace (duh) and how Christianity killed during the Crusades.  I think he has forgotten that Islam has been doing killings in the name of Allah since the 7th century and not Christianity. But, Obama did add that Jesus Christ is responsible for slavery in this country.  I had seen these videos before, but apparently did not catch this slight at Christianity.  I do not know where he learned this false and outrageous claim, but we do know that he was raised a Muslim in Indonesia and could be this was what he was taught.  This is why his sympathy always lies with Muslims and goes on the offense whenever Islam is associated with terrorism.  Makes one wonder what religion he really belongs too.
