You assumed incorrectly on both counts.
And I will not disagree with you that Lib has been a cantankerous ass the last few weeks, but, at least to me, it seems to be behavior that is inconsistent with what his behavior had been during the months prior - hence my concern as opposed to my ire.
However, there is only so much concern I have to spare for those who will not help themselves, and I hope, in time, those who need help will get it. Until then, by all means, call assholery wherever you find it - it deserves to be confronted, regardless of the root cause.
