I'm fully aware of what Islam preaches. You in turn preach the same thing in regard to Islam. Forcible conversion or extinction. If you condemn Islam you condemn yourself.
I fully understand your discomfort; it's not a pleasant situation to be in. But we are not in this position by our own choice, and if you value or love anything in life then you must resolve yourself to the only choice they have given us. Kill them, or die ourselves. Every possible middle ground has been tried and failed. Must I list the peoples and nations that Islam is right now making war upon to make this clear?
If you've got another solution I'd be quite eager to hear it. "Criminal prosecution" bought us 9/11, so I'm not going to buy into that one. Deterrence doesn't work against people who believe that they are promised eternal paradise if they die while trying to kill you. And treaties and truces are nothing to them but the opportunity to resupply, re-arm, and plot our deaths. What other option are we left with?
