He writes:

I rarely wrote about Hitchens because, at least for the time that I’ve been writing about politics (since late 2005), there was nothing particularly notable about him. When it came to the defining issues of the post-9/11 era, he was largely indistinguishable from the small army of neoconservative fanatics eager to unleash ever-greater violence against Muslims: driven by a toxic mix of barbarism, self-loving provincialism, a sense of personal inadequacy, and, most of all, a pity-inducing need to find glory and purpose in cheering on military adventures and vanquishing some foe of historically unprecedented evil even if it meant manufacturing them.

And later:

Nobody should have to silently watch someone with this history be converted into some sort of universally beloved literary saint. To enshrine him as worthy of unalloyed admiration is to insist that these actions were either themselves commendable or, at worst, insignificant. Nobody who writes about politics for decades will be entirely free of serious error, but how serious the error is, whether it reflects on their character, and whether they came to regret it, are all vital parts of honestly describing and assessing their work. To demand its exclusion is an act of dishonesty.
