This thread reminds me of the many other instances I've seen, of people who weren't around in the 90s, or were children, taking one-dimensional information as gospel, about 'how life was and what people thought'. It's really fascinating, watching people mangle such recent history to their own one-dimensional ends - but more than anything, their determination that they are right, based on so little.
For example, I've heard British people say 'there's a lot of homophobia in Friends but that's just how backwards things were in the 90s'. Whereas, watching Friends in the 90s, I, like most British people, thought 'Joey, you casually homophobic twit, you're embarrassing, stop that!', while also recognising that Joey is a character, drawn as having grown up in very traditional, patriarchal family (likewise Ross, Monica and Rachel) and as being intellectually challenged, someone likely to parrot his father's social attitudes without reflection, unlikely to give deep thought to social issues. Likewise Ross, clever about some things but socially clueless. We were meant to be cringing and laughing at them, not with them.
I don't think I did that to my parents' generation about the 1960s. I think I listened and understood I hadn't been there, so might know facts but not the nuance, the life, the context.
