On the contrary, if you wish to learn about Chomsky's views towards the Khmer Rouge, the onus is entirely on you to investigate Chomsky's work. Failing that you're entirely at the mercy of intermediated secondary sources of indeterminate levels of trustworthiness, including myself.

Considering the nuanced nature of the claim - a conclusion as to his sympathies borne of deep familiarly with his work - there's no reason for me to think you wouldn't find additional reasons to quibble over any specific citations and passages. I have no evidence that you're a good faith interlocutor, so I really see no reason to expend that effort. If you're actually interested, I do encourage you to read the original works. (If it wakes you up to Chomsky's sympathies and immunises you against some of his bad politics, perhaps not a total waste of time.)
