I disagree.

With what? That there can be valid grievances with Western policies? That anyone could have a valid reason for hatred?

If you killed my brother, I'd have a significant feeling of hatred towards you. You can call me a coward all you want, but my feeling would be 100% valid. Now apply that principle to the tens and hundreds of thousands of families that have had Western gov'ts kill their civilian family members (as collateral damage). Those Western gov'ts may have reasons they consider good for having killed those civilians (or causing the deaths, however you want to think about it), but you cannot expect the surviving families are going to nod their heads and say "OK, I guess it had to be that way".

I think this quote puts it in perspective: “Hatred is self-punishment. Hatred it the coward's revenge for being intimidated.”

It doesn't, really.

let's not throw out the baby with the bathwater. The truth is always somewhere in the middle.

... and an apple a day keeps the doctor away? "Hatred does not cease by hatred, but only by love." The truth is staring you in the face.
