The problem is anger: it fuels the extremism which seeks to control through fear, which in turn makes us all angrier!
These terrorists (in Europe in recent times almost all 2nd or 3rd generation, home-grown petty criminals seduced and given a twisted Big Idea by ISIS websites) are angry and want to incite us to lash out like they do, to prove them right in their angry hatred of us. But 'an eye for an eye makes the whole world blind' (I won't go into teeth at this point if you don't mind - a sore subject). However angry we feel in response to these attacks, if we let our anger guide our actions then we're doing exactly what they want us to do - turn on our fellow citizens of whatever hue or culture, blame them all in an angry sweep, and join in adding to the sum of human suffering.
Our response has to hold firm to our values of tolerance and compassion - one race, the human race - and be intelligent and targeted, which, in general, I think it has been, because (thank God, or Whoever) we have laws which protect the rights of individuals, wherever they might have come from out of our colonial past. Just as the americans can't (or choose not to) legislate for the crazies who open fire in primary schools, we can't lock up or kick out every muslim because of the actions of a few (and I do believe they are few - it's not even one thousandth of one percent who do this shit).
I think the kind of 'Je suis Charlie' response we've seen in Manchester and London - don't let the buggers grind us down - is the right one, not because it denies how fearful we might justifiably feel, but because it doesn't let them see our fear. The way the Norwegians refused to lash out after the Britvic (?) shootings was, I believe, exactly right.
They're not winning! They're not even a flea on a pregnant elephant. Millions of us, every day, enjoy freedom of speech, of sexuality, of political and religious belief, the fruits of centuries of gradually accumulated wisdom and understanding of how to live in peace with each other. So long as we hold true to our humanity, we win and always will.
