I agree with your analysis. The West needs to come to grips with the fact that Islam's mandate is "convert or kill" the infidel. Islam has been trying to fulfill this mandate for, oh, around 1200 to 1300 years!
When faced with such an intractable enemy, to survive, unorthodox measures may be required. And it is a question of survival, in my opinion.
This crap about trying to "understand" why they are the way they are is the usual "liberal bs, just like "crime is caused by poverty".
Islam is the problem.
It's the usual liberals' bs and the more and more usual lib-cons' bs.
