Be specific. "Well just look at <general direction>" is a horrible way of discussing.

And about your thought: I disagree. When I look at those online places, I see echo chambers, trolls and a lack of critical thinking (on how to properly discuss a topic). Some parts might be artificially accelerated, but I don't see propaganda couldn't be fought. People are just coasting, lazy, group thinking, being entertained and angry.

Lack of critical thinking is a key success indicator for propaganda.

Propaganda is less about what it says, but more about how it makes people _feel_.

If you get the feels strong enough, it doesn't matter what you say. The game is over before you start.
