…that were shocking back then, but aren’t nowadays:
1. Miniskirts

2. Women getting tattoos

(pic from 1940)
3. Interracial couples

And three things that weren’t shocking back then, but are nowadays:
1. Candy cigarettes

2. Fewer safety regulations

3. Letting kids play outside, unsupervised

Shocking then but not now:
4) lack of manners
5) dressing like a slob to go to the store
It was a better time.
Fat kids and teenagers.
It was one thing to see an overweight adult, but not kids. And even teenagers – what we thought was “fat” would be positively healthy looking now by comparison. I can recall only about three people out of a 500 person high school that would be considered obese by today’s standards.
I’d submit:
Trannies. Shocking to the point of arrest then.
Today, still revolting, but everyone pretends to ignore it.
Then – Tattoos on the occasional WWII Navy / Marine Enlisted Vet ( never an officer )
Now — anybody under 35 who DOESN’T have multiple highly visible tat’s.
Then – modesty
Now – narcissism
