One of the biggest failures of the left is its reactionary defence of Islam (as a religion).
Any honest criticism of Islam is branded Islamophobia (similarly to how any criticism of Israel is conflated with antisemitism).
Regardless of whether one wants to blame the Quran, or the cultures of Muslim communities - the fact remains that people get killed in non-Muslim majority countries for trivial shit.
I could draw a picture of Jesus sucking off Joseph Smith and I don't need to worry about Mormons coming to kill me.
