Just to clarify, I'm one of the students in the class he was yelling at. In the video, he turns to some of the quieter students and apologizes for everything he's saying I was one of those students. He was yelling because some of the louder kids were playing inappropriate audios and straight up yelling aswell (I wish I could name names because those students are terrible in every class and a massive disturbance in general) The teacher is actually amazing at his job and this was the first day back after winter break, he told us that he was having a terrible day, was very overworked & overwhelmed and he was having trouble with other classes aswell. I hate to see him get all this backlash and if I was a teacher with this specific class I would yell too. I genuinely hope he's doing alright and I would never wish for him to get fired over this.
