I think as the younger generations come of age they simply will not care about that sort of thing. Like it or not, it's part of the culture and might just be accepted as the norm.

I think it's kind of happened already. All the time we see news of politicians or famous people having their very old photos, comments, or reddit accounts found with distasteful takes. And it seems they can mostly just handwave it away with "Hey that was 10 years ago and I wouldn't make those comments today" and nothing seems to come of it.

They might not care about it themselves but what about their government?

When the younger generation comes of age the new younger generation will have a different culture and norm what is acceptable.

People got in trouble for things they posted years ago where they didn‘t care but others did
