I'll try to stay off of extremist places like the Ivy League. Thanks for the link.
Even though I am not now, nor have ever been a member of the Jewish faith, I've been verbally identified and attacked by lib antisemites countless times during my life. If I had a dime for every time I've been called a "GD Jew boy" , "Christ Killer" or "K***" by a lib I didn't know, I'd be a wealthy man. So I guess that makes me "visibly Jewish"?
Sorry that happened to you. So senseless and cruel regardless of whether you were Jewish or not. Good people teach their children not to do that. Good schools instill good manners, courtesy, kindness in their students.
I had most of my public schooling in the "Little Texas" area of southeastern New Mexico, 17 miles from the West Texas state line. Mostly rough necks and red neck business people and rancher/farmer types, fiercely independent, mostly Christian.
Schools were segregated much of that time until our little town decided it was stupid for the black kids to be bussed 20 miles to the 'black school' and decided to integrate years before Jim Crow laws were made illegal. Because we had God fearing administrators and teachers who coached us in courtesy and diplomacy, the white kids took in the black kids as friends and to the best of my knowledge there were no ugly racial incidents.
Many adults had grown up in deep south culture and swallowed hard when the kids started bringing their black friends home to play, for dinner, for slumber parties, etc. but they stepped up and handled it like troopers.
We knew some of our classmates were Jewish too and didn't think anything about it. The junior high and high school choir director at some point became aware of the Jewish students among us and included some Hannukah songs in our Christmas concert and the Christian kids enjoyed singing those as much as the Jewish kids enthusiastically sang the Christian songs. No KKK or other racist groups in our part of the world then.
It really is possible for people to get along and coexist peacefully and productively. The KKK and such racist groups were in decline and ill repute. Were there racists among us? Of course. Did they have any power? Nope. They were just shrugged off and the rest of us got along just fine.
I think this positive cultural shift started to change when the Atheists got together and started suing towns, schools, public facilities etc. who acknowledged the Christian faith in any way. And made worse when militant racial groups got militant instead of pushing for peaceful integration MLK style. And anger and hatred began to grow again instead of decline. And some began to make an industry out of and get rich by race baiting and it is those who are perpetuating racism, antisemitism, anti-Christian forces and other uglies in our society now.
