Age Gap Friendship discourse

Has anyone else noticed this really weird infantilization thing going on among young adults lately? You have people in their 20s acting like they're still 9 years old and it's weird for anyone 2-4 years older to even speak to them.

Maybe it's because I'm about to be 30 myself, but why does it seem like people are being trained to assume that adults older than 30 are predators in wait?
