If what they're saying about Bale's reasons are true, and the transcript certainly backs it up, then he may have gone batshit insane (hahaha) but he's not unjustified. I've certainly felt like doing similar in college theater when people were acting stupid or unprofessionally. I really can't blame Bale. Plus his diatribe was clearly aimed at the actions of the man, not the man himself. "I can't work with you" not "You'll never work in this town again."
