Literally none of Danaher's arguments make sense.
He portrays Davila as an incompetent loser, but he won two matches. Apparently that's not good enough to enter a tournament folks. You need to understand your place.
He claims, without support, that having Davila blocked EBI from taking Tonon. What evidence? If you believe that there was a discussion in which EBI rejected Tonon because of Davila, lay down the crack pipe. EBI is a business and will put on the best fights it can, period. The idea that EBI told Tonon 'no, not taking you because Davila sometimes trains at your school" ... That literally never happened, Danaher doesn't claim it does, and his intimation this was the issue has no support in evidence.
Danaher was pissed that his vision of who should fight at EBI wasn't followed in every cult-y specific as dictated by the omniscient grand wizard. His students were irked that Davila entered and got a spot by pushing for it. And that implies the grand wizard's commands weren't sent down from Allah. That implies his underlings have free will, which is intolerable.
From memory of the post (I've only read it once when it was originally posted on social media) he did give Davila his due in that he did accept he beat grapplers like baret Yoshida to advance.
