Student drew a 3rd Reich flag with the chromebook in my class today.

I lost it with a class. A student made a Third Reich flag on the Chromebook in my class. Heard hitler and looked over then I went off in a profanity laced tirade about how many people died and they were not all Jews and you in a Parochial school. Showed a Holocaust video for the rest of the day for the rest of my classes. The video went went well and had some discussions I really don't need this job and may get fired but it's a good hill to die on.
