Is that good wording for a logician? Just asking, but for a dumb fellow like me it seems that "can't bear" indicates an anxiousness to see the reply and "predictable" means you already know what it is going to say. Can you really look forward to something you already know, especially if you disagree with it? Again, just asking.
Anxiety has nothing to do with it. "Can't bear to wait" means just as it says: I won't -- and didn't -- wait for takeit's state-loving, groveling remarks (assuming he/she/it ever bothered to read the thread), which have become very predictable when any topic concerning federal police agencies' malfeasance and misdeeds is being scrutinized.
But I think you knew that already.
