I'm hardly a Muslim hater and frankly don't care one way or the other about most religion as long as it's peaceful.
That being said I'm with the dad on this one and in general can't stand people's religious values being thrust upon society. Keep them in your church/synagogue/mosque/temple.
Some of the issues crop up because where public facilities are involved, and Muslims are a significant part of the tax-base - then I think they do deserve to have some degree of accommodation to their beliefs. Not sure if that's the case in this specific instance, though I do think that Toronto probably does have a fairly large tax-paying Muslim population.
