Oh, I agree, and have for some time, that those Tweets certainly seem to INDICATE the behaviour/sentiment you discribe. But I don't know it yet.
It's this "conjecture passed off as fact" that I keep coming back to here. To pass that interpretation of two brief & months old Tweets (by what we suspected at the time, I recall, was a non-native English speaker) as a sweeping proof of an individual's motivation & intent is simply unsupportable.
