Looks like his lawyers have written a statement for him. I doubt anything happens to him although I feel like some discipline would be appropriate.
I am 62 and have never said that word. When I was in high school, I heard it said by boys frequently but never girls. I never heard it at our house either and I had four brothers.
Being Catholic in small town southern Iowa, I did hear slur words about Catholics frequently as well. One of the high school teachers brought in her husband’s KKK robe and hood for some bizarre show and tell. The handful of us Catholic students, the two Jewish students, and the three black students all tried to decide at lunch one day if it was aimed at all of us or just a select group or two, or if the teacher was just clueless in general. My brothers were old enough to remember the Klan burning a cross in our churchyard, but it was before I was born.
Your School had Jewish kids? Way more diverse than mine. The Klan robe thing is crazy though.
