In general, I agree, but I think you make it sound easier than what will be considering the extent the extremists with the cooperation of Western leftists "own" the major institutions of that religion.
On the following... well, what can I say?
The effects of Islamofacism on their children will be every bit as invasive as the invasive effects of British Tyranny on the descendents of the founding fathers.
The "British Tyranny" would have resulted in exactly what for the descendants of the Founders? They would have ended up like Canadians or Australians?
It's a poor analogy that trivializes the very real danger to all of civilization posed by radical Islam.
We wouldn't be Americans, there wouldn't have BEEN an America...and we might very well be speaking German or Russian and all be living in a Nazi or Communist empire.
Yeah, I guess I do make it sound easier than it would be. In my experience, I have found that people who enact change are the ones who don't wring their hands over the "nuances" but instead get to work fixing the problem. I don't make "perfection the enemy of action". I will throw my lot in with those people.
