If this was the only time he did it I would agree with you.
Here is the thing, I even agree with him most of the time and for the most part I like his comics even though he never met a plothole he couldn't ignore for funsies

and he has more comic knowledge than I could ever hope to and he knows it which is both interesting and slightly off-putting. All he has to do is be a bit more diplomatic and he wouldn't sound as bad. He has never done that...not since the premiere of the film and in my eyes (and I am only speaking for me) it has made him look childish.
I mean I guess that is better than Gail Simone who basically tweets a novel about her love of everything that uses a character she loves...but still.
