Here's the practical consequence: when we accept method acting as a justification, every jerk on set gets a noble excuse. A performer can scream at crew, isolate coworkers, or wreck takes, then call it process. The people who suffer aren't audiences; they're the people who can't walk away. Art doesn't require casualties. If someone needs to abuse people to act, that's not talent, that's a bad coworker with a stage name. My opponent can dress it up as dedication, but excuse-making is the point. Judge the behavior, not the backstory.
