okay okay, that's nice, much previous credential very awe! I, too, am capable of looking up someone's past! (and in fact I did)
but again I ask you: can you argue _why_?
you make a substantive claim that someone else is wrong, with no argument as to why other than "bc he said so!", a naked appeal to (perceived) authority
if you want to argue a point, *argue a point*. bring your points, I'll bring the snacks!
