You know at first it was funny, but now it just looks petty.
Legit questions when encased in a howling attitude of 'certainly' do not lend themselves to a label of "petty" when time proves them incorrect, despite suggestions by those whom an op may not feel has an understanding of a process which they themselves do not possess.
To some, it may look petty for an individual who rabidly promoted a position to attempt to defend themselves against a truth that they themselves didn' t acknowlege at the time they rabidly defended a given position!
