I grew up in the 70s outside of Baltimore. A new town called Columbia. Mostly well off but My neighborhood had brand new section 8 housing and obviously it was filled with blacks wanting to leave the horrors of downtown Baltimore. My high school was 60% white, 35% black and 5% everything else. Of that maybe 10% were Jewish. Mostly people moving from New York to afford a nicer house. Until high school my friends were a mix of blacks and whites. After that we split off into tribes. I tell my kids the horror stories. I got beat up regularly by black kids. Whites routinely called black the N word and other words in regular conversations. It was very common. We had a couple of race riots in school. Drugs were everywhere. Smoking was allowed in the school. We had a freaking student smoking lounge! Keg parties every weekend in the woods or some random house with the parents upstairs. I lost a few friends to drunk driving. And this was in a nice suburb! My kids just went through high school a couple years ago. Nobody hardly drinks. Some vaping. No cigarettes. I only heard of one bad drunk driving accident in the six years I had kids in high school. Albeit we live in one of the whitest parts of the country. Seattle area. But we have Indians. Japanese. Chinese. Koreans. Africans. We had more African kids than blacks in our school. It’s the tech industry here. All I’m trying to say things may have somewhat simplified back then but it wasn’t easy.
