I heard all the information on various sources regarding this teacher, and I still think she is in the wrong. Not enough for protests or removing her, but I think she should have been more aware that her autistic student was moving toward the microphone and at least asked him what he wanted to say. “Gobble gobble” would have hurt nothing, likely made most folks laugh or smile, and been a cherry on top of the ice cream sundae.
She was likely running on an autopilot to get the program moving because most programs with children that age run longer than anticipated and wasn’t paying real attention. It’s a mistake, but not an intentionally disrespectful or harmful mistake.
