So Muslims get to pray 5 times a day at school intimidating everyone else and making a mockery of the idea of public education, secularism, the Enlightenment, etc, just because it's not part of their religion.

From an education standpoint this is not good.

What's the chances these Muslim students will ever pick up a book on western philosophy: say, Bertrand Russell or David Hume? Answer: no chance. 

We should not be enabling anti-education attitudes at school. That includes having prayer rooms. That's what ISIS would do. Get real, Canada.
