He said "most times", not "anyone". You're conflating his broad assumption to an absolute statement, which it was not. I disagree with his assessment, but also your assessment of his assessment.
That said, you're right - I've not seen any earlier statements. I just saw a claim that people were being attacked, read the last bit to find a comment on the matter, figured I'd found it, and commented on it.
Frankly, knowing CM at least as much as I do, I can tell you with some certainty that he wasn't likely attacking anyone, rather just making confident claims based on things he assumes to be true. Doesn't make him right, but I've not known him to be malicious.
If he or anyone is actively attacking anyone, I'd appreciate that sort of thing being reported, rather than dragged on.
