Never said Batman was arguing that, I was just pointing out the irony that the rest of the league was debating one member lying when one of their premiere members basically had a super secret on all of them. Although I am sure Batman would just say "you never asked, I hide nothing"
I do have to say though, the league meeting the way it did brought a sort of real nature into the ordeal. I have been in a lot of corp and business style private meetings that were just like that over the past 20 years. It was kind of refreshing to see that even the mighty heroes could be just as petty and biased in what is essentially a superhero defense corporation.
