There seems to be some confusion here about which Slavs settled on the prairies. In your ignorant Muslim mind, you seem to think only of Yugoslavia, when this is clearly not the case. The Slavs who settled in the western provinces were from the Ukraine, which at the time was solidly attached to the Russian empire. Thus your question is irrelevant.
Hostility to Muslims has existed continuously since before the middle ages, and with good reason. Nobel prize winner Ang San Sukyi can hardly be considered a bigot, yet she didn't hesitate to kick all the Muslims out after they started an insurgency. In this, she showed greater wisdom and courage than Trudeau ever will.
