Older people didn't like a kid telling them they destroyed the world through selfish ideals.

Propaganda.

Basically because she was a child and their egos were hurt that a child would dare to criticize them.

She went from vague calls to action on climate to root cause analysis. The root causes didn't like that.

Personally I find she falls in to the category of people who protest things we already know are bad. So I think all she does is self-promote and accomplish nothing. I don't disagree with her on any of the things she chooses to fight for, but I think she chooses the least effectual way to fight.

Great, she's shown the IDF are a bunch of cunts who are preventing aid reaching Gaza. We knew that. What's changed? IMO all she's done is move the camera lenses from Gazans onto her for a while.
