Extreme biased article.  The Globe repeatedly quotes Imam Ibraham Hindy.  This Imam invited a Egyptian "Scholar" to speak at his mosque. The following is an excerpt from the  "scholar" . Salafi Shaykh Nash’at Ahmad‘s sermons in Egypt (originally in Arabic):
January 6, 2016: “O Allah, destroy the Jews and whom they ally with… count their number; slay them one by one and spare not one of them.”  
The Globe would be well advised to hear the concern of parents who do not wish Islamism promoted in the public schools.  Prayers and sermons should be done at home or in the Mosque.
