Do you seriously not see the irony of claiming that fundamentalism reduces one to their most base of tendencies, while espousing exactly such behavior as a response?
We were all once barbaric (in many, many ways, still are). How did we get out of it? Education, not by some enlightened assholes blowing us up. Please take a step back from your emotion and think about what you're saying.
He is simply saying that you should not bring a lollipop to a knife fight. Verbal confrontation and physical confrontation are very different. Trying to educate your opponent might work in a discussion on the merits some technical issue but will only serve to further provoke that drunk guy in the bar that wants to smash your face in.
For some of us this lesson is hard to learn. But if we die because we did not learn it, it is the ultimate game over - you cant retry with a different perspective to win the argument, you lost. This changes the risk/reward scenario and being "nice" will not cut it. You will need to do everything in your power to prevent such irrevocable loss, including those things you would prefer not to do.
Again, I'd ask you to reread what I'm proposing. I am not proposing the wholesale slaughter of those who believe differently than I, nor am I saying we must force our values on others. We must, however, defeat this foe. Where education and economic freedom can accomplish these goals, we should use them. However, the true nutbags will not be deterred by these means, and in fact actively fight against them. You can not educate away the Bin Ladens of the world; he in fact was very highly educated in Western schools. Where religious fundamentalists seek to destroy our culture with violence, we must be prepared to respond in kind.
Again, we didn't start this fight and we cannot coexist. This is not a matter of live and let live, as they won't let us live. The fundamentalists are expansionist, and are not happy unless everyone believes as they do. Take this attack, for instance. In Islam, you are forbidden from insulting the Prophet. Fine. If you're Muslim, then don't insult the Prophet.
That's not enough for them. They want everyone else to follow their dictates, too. Where they are not followed, these people think it entirely reasonable to murder innocents unconnected to the original "offense". Our only options, here, are to either respond with force or acquiesce. If we choose the latter, we have abandoned our values of free speech in favour of their values of adherence to their dogma. This cannot be.
