The problem is though that even if they "just think it's funny", over time it gets built into their worldview.

It's like people who only consume TV shows and movies, they know it's all fiction, but if you talk to them about how the world works, you realize that all their mental structures are based on Hollywood tropes.

This even tracks to reddit, where everyone knows it's bullshit and reddit is dumb, but their entire perception of the world is still reddit's dumb views anyway.
