What you did, referring disparagingly to "Greta and her disciples":
https://www.grammarly.com/blog/straw-man-fallacy/
"A straw man argument is the logical fallacy of distorting an opposing position into an extreme version of itself and then arguing against that extreme version. In creating a straw man argument, the arguer strips the opposing point of view of any nuance and often misrepresents it in a negative light."
Not only does Greta know a damn sight more about the issue than you seem to, she's shown on many occasions that she understands the difference between emissions in use and total CO2 burden (including manufacturing/disposal and other overheads) of many things, EVs included -- and that though EVs may not be perfect they're much less bad for the planet than ICE.
An equivalent argument would be to refer to people like you as "ignorant petrolheads" who don't care about the planet and just want to carry on driving your massive gas-guzzling SUVs everywhere, including to the shops and taking the kids to school... 😉
(which I'm sure you not -- but it's the same type of argument you're putting forward...)
