It would cost Canada nothing to declare a ten year moratorium on immigration from any nation which styled itself an “Islamic Republic” or which either directly or indirectly encouraged radical Islam. (I suppose we might make an exception for England but, frankly, it is a close run thing.)
Islam, in its radical form, is simply incompatible with Western liberal democracy. Sorting the Muslim sheep from the Islamic goats is a process far too complicated to be undertaken on a mass scale. So, for the moment, it makes sense to say that no one from the cesspools of Islamic thought should be allowed into Canada. There are plenty of deserving, terror-phobic, potential immigrants who would be more than happy to take those places opened by a ban on Islamic immigration.
No doubt such a policy would be condemned as Islamophobic. So what?
A well-regarded Canadian newspaper columnist told me earlier this year that, were s/he to express such views in public, his/her career as a mainstream writer would be finished.
I have a feeling we’re about six months away from that view seeming adorably quaint.
You can thank me later.
