Greta : 8 items
Memes-Greta - Greta is the poster child (literally) of the cry-bully left: exploiting a special needs child for sake of their fascist (anti-progress) agenda. These are the memes that tell the story.
Greta's Daddy -
End of Brady - To show you what FakeNews and how self deluded The Atlantic has become, this quote sums it up. While discussing the final demise of Tom Brady and the Patriots, Scott Stossel (National Editor) said, "He’s like Thor, or Superman, or Greta Thunberg—when everything looks lost, he arrives to save the day." Two are fantasy characters, Scoldilocks (Greta) hasn't achieved except ditching school and lecturing people that know more than her on a cause she doesn't understand, while Tom Brady actually achieved something in real life (cheating at football and cheating on his wife). Apparently the Atlantic can't tell the difference between those things.
Russian Prank of Maxine and Greta - Maxine Waters was pranked by Russian trolls with a fake call to Greta Thunberg about how the Fake Climate Activist had dirt on President Trump. Anyone with a triple digit IQ would have seen through advocating for the protection of the fictitious "Chon-Go-Chango" islands, and went on to imply all sorts of nefarious things Trump said to Scoldilocks. Unfortunately, nobody has accused the Hypocrite from Southern California of having a triple digit IQ, so she gobbled it up and tried to setup a meeting to create another mock scandal.
The Greta Train -
Trump Cyberbullies Greta - The far left (like CNN) is outraged that Trump is "Cyberbullying" Greta, by pointing out that a spoiled little school ditcher has "anger management" issues, and she should probably just relax and watch a movie, after she calls for Politicians to be put against the wall. Ignoring that's not really the criteria for cyberbullying (to the reasonable non-CNN watchers), Greta claims it was just a misunderstanding between Swedenglish (a mistranslation) that's the root of the problem, even though she's said worse a dozen other times, in many different ways. Oh, and they claim that Melania Trump is a hypocrite for wanting to protect her non-activist younger child from the ravages of a venomous Press, because she won't criticize her Husband for attacking political figures who made themselves the voice of a cause and attack him first. It's eye-rollingly dumb, but then again, this is CNN.
Greta Man of the Year -
Severn Cullis-Suzuki - Not much different than 1992 Severn Cullis-Suzuki doing the same ranting ignorance over 25 years ago at the U.N. Earth Summit in Rio de Janeiro, with the same dire warnings about immediate pending doom, in which nothing happened, and nothing bad happened as a consequence. 
It is like they have the same PR firm, and same political agenda, telling the same scarism: give up your freedom to us, to fix this, or the sky will fall.
This isn't the first or 50th times kids have been exploited and abused in this way. Despotic leftists use Children as props, and program them with the same propaganda and disinformation, to tug at the heart strings of the gullible. Because if the listeners brain-strings engage, and they do any basic research, they're no longer pliable tools of the left.
So what did we learn. Trick question. If leftists could learn, their ideology would go extinct. They'd realize we live in the best time to ever be alive as humans, and thus the dire need to give up your freedom to some international protection racket, is about the dumbest thing you could do. Their goal isn't the environment, or they wouldn't all fly there. Their admitted goal is about remaking the world economy into a Communist and Collectivist utopia, and they're testing and programming people to be good enforcers of the states agenda.
Her tantrums are a failure of her parenting. Her beliefs are a failure of education. And her passion and self righteousness is a failure to teach moderation. She's a fanatic, and those stories usually end poorly. The best case is that they eventually grow out of it, and realize how much of their lives were wasted/robbed from them. The worst case is they self-destruct as they continue their intellectual death spiral into breakdowns over not getting their way, and become a soapbox preacher or the next Ted Kaczynski. Which begs the questions:
This is kiddie porn for the Enviro-extremists. And we should not celebrate or sensationalize it.
