I agree with you 100%, but I would add the bubble effect.

You watch something, you like it, then you get all the time similar things.

Simple example: you click on a post about vegetarian meals. Then the next you see is cows ending up in a slaughterhouse. And then etc.. In less than a week, your posts are all about "why become a vegan".

The end effect is that they shape our children culturally, and it's very hard to explain what is true vs what is fake. Or why something is right vs wrong. They are just not there yet.
