You can just post this question at any point in the past 50 years and there will be a lot of people who agree with you and pull something out of history.

Because it’s in the immediate now, it feels like the most extreme thing.

If you want to get even farther (and fall into a spiral), you can actually review the past 200 years. Early in the 1900s, we invaded the Philippines. In the 1800s, we were massacring natives/indigenous people.

These are extremely broad strokes I’m emphasizing.

And again, this is a rabbit hole of darkness and I don’t recommend subscribing to the “everything is shit” philosophy. But take a step back into history and do recognize that there has always been a significant (in your words) level of stupid, a low point of intellectualism and accountability.
