To read this quote from Kerry and see it as endorsing or excusing in any way the Paris attacks is purely a result of partisan preferences. He's clearly describing
the rationale behind the terrorist attack, not giving endorsement to said rationale. And you're not even providing the full quote, just a tiny
exerpt from the full speech he gave. He goes on immediately after this to say
"This Friday was absolutely indiscriminate. It wasn’t to aggrieve one particular sense of wrong. It was to terrorize people. It was to attack everything that we do stand for. That’s not an exaggeration. It was to assault all sense of nationhood and nation-state and rule of law and decency, dignity, and just put fear into the community and say, “Here we are.” And for what? What’s the platform? What’s the grievance? That we’re not who they are? They kill people because of who they are and they kill people because of what they believe. And it’s indiscriminate. They kill Shia. They kill Yezidis. They kill Christians. They kill Druze. They kill Ismaili. They kill anybody who isn’t them and doesn’t pledge to be that. And they carry with them the greatest public display of misogyny that I’ve ever seen, not to mention a false claim regarding Islam. It has nothing to do with Islam; it has everything to do with criminality, with terror, with abuse, with psychopathism – I mean, you name it."
