If I were married with a child and this happened to my kid...I'd tell my wife that it's okay to beat the shit out that woman. I'll pay all the bills until she can find another job in case she gets fired from her current for punching that teacher.
We're not going "educate" that teacher, we're not going to empathise with her; you can summon whitewashed MLK and write long winded dissertation about loving your fellow man and being the bigger person, it will be ignored because this teacher...she WILL catch a fade, if my s/o didn't do it, then I'd have a family friend do it. But an ass whoopin WILL be administered. Wallahi
Maybe choking people is her way of criticizing Islam? I dunno I feel that calling someone Islamophobic is really problematic. It's like calling someone racist, you shouldn't use that unless you're 100% sure! Those words ruin lives, think about that person's career and family!
