Unfortunately I like motor vehicles too much to be an environmentalist; the older bigger and noisier and smokier they are, the more I like them, e.g. 1960s Land-Rovers, steam engines, vintage buses. My first word was "tractor". Sorry, planet: it's not that I don't like you, I just like other things more...
However, at Greta Thunberg's age I was too busy feeling sorry for myself to campaign for anything bigger than my next pizza. From one interview with her that I remember reading, she's already come through that phase and way out the other side of it! I believe in the same interview she also revealed she'd been anorexic in the past. It takes amazing determination to pull yourself out of that.
Hooray for the fact an Aspie is out there being passionate and articulate, thus proving to the world that we can have feelings and can, in some way, engage with the rest of the human race. Quite honestly I wish the media would remind NTs, every time Greta Thunberg is mentioned, that she has A.S.D. I guess she herself wouldn't necessarily welcome that, though. But it seems to me she is a great ambassador for the condition, and I love the way she refers to her Asperger's as a "superpower": reminds me that there actually are a few things NTs have said I was really good at, even though there are a lot of things I'm terrible at.
She may have affluent and somewhat indulgent parents, but you can't blame someone for being born into a certain household any more than you can blame them for being born neurodivergent. Nor can you blame the parents of a girl who used to be withdrawn and depressed for supporting her when she discovers some motivation for getting out of her bedroom and doing something.
