There is far more hate going on within Islam these days than there is between Christians and Muslims.
Just the other day I asked an educated Sunni Muslim friend what she thought of the Ismaili Shiite sect (Aga Khan is leader) and she came right out and said that "they were not Muslims".   I was shocked.

Then we have the Saudi Sunnis angling for dominance over the Shiites from Iran.  And look at ISIS killing their own religious brothers and sisters if they are Shiite or not orthodox enough.   Where are the articles from this author suggesting that maybe Muslims need to look within and solve the sectarian problems in the Middle East before they run away to the safety of the West and then go apoplectic over a country wanting to keep those same ME problems out. 

Hirsi Ali is correct in that Islam needs to clean up its own house before it starts lecturing those of us that have moved beyond sectarian hate long ago.
