We are pretty similar in age.
> I feel like in last 6-8 years, people have become far more intolerant regarding free speech.
Which people, and what speech?
I grew up in a smaller town (but not tiny), where teachers who were fired or otherwise quietly left town after coming out as gay.
My parents stressed about petty church politics because good standing in the local church had a direct effect on their ability to get and keep (completely secular) jobs.
They put out yard signs for candidates they secretly voted against.
If you weren't a white right-of-GOP-center conservative evangelical christian, life was an exercise is constant self-censorship.
From my perspective, "cancel culture" doesn't really seem particularly new. On average, people enjoy more expressive freedom today than they did in the 1980s.
So, again: which people, and what speech? Perhaps a few major metro areas enjoyed true liberalism re: speech in the 80s; I wouldn't know. But in most of America, your golden age of free speech never actually existed.
