For the next few days, weeks, months, the usual suspects will channel their fears and hatred towards both those who murdered in France two days ago, and those who disagree with them on how to tackle it. They'll whip themselves up into a hatred-filled frenzy against those who are unfortunate enough to share the same religion as the terrorists, and they'll blow the "threat" up out of all proportion.
These people are simply stupid. Don't get angry at them, ignore them. They're victims of terrorism in its purest sense - they're the people shitting their pants at what just transpired, in a way nobody in Paris, New York, or London is doing, or will do. They're weak, scared, and pathetic, and they're lashing out at everyone from ordinary Muslims to Liberals because ISIL just played them like a violin.
Tomorrow is another day. It'll be like Tuesday of last week, except there'll be 150 or so fewer people to enjoy it thanks to a group of religious extremists who represent nobody but themselves. We'll miss those who are gone, but life goes on. Dealing with those who cause such horrors involves reason and human decency. ISIL's plan involves us having neither. Their success requires we have neither.
But we're better than they are.
