Many things we recognize as terrible now were recognized as okay years ago. People then were blind to it. I assume I have similar blindnesses (e.g. In some of my social circles, using blindness as a metaphor is considered ableist). I know my own opinions have shifted in recent years from things I used to consider cringey PC bullshit to "oh they were right on this one." I remember some jokes I thought were funny as a kid (ones I even repeated to friends) which I think are disgustingly offensive now.

The scary part is that with such a strong digital record, people recorded as having now-bad opinions are being held to account all over the place. Sometimes they go viral and lose context, making them seem truly evil. They should be fired from whatever their job is today and shunned, apparently. Or elected prime minister of Canada. It's unpredictable.
