Two things left-wingers don’t like in 2015: Jews, and saying anything negative about Muslims.
Since any observer looking at the plain facts sees that there is much deficient in Islam, the only thing they can do is repeatedly announce that criticism, discussion, or observation of Islam (“Islamophobia” is their word for it) is not allowed. The rest of us can choose to abide by these decrees, or not. For people like the Jews of France, abiding by them means death, but the left has made it clear that there is no number of dead Jews that they will acknowledge as a problem – or a reality – if it means admitting that Islam is anything less than perfect.
