Strukturelles Versagen

Klimawandel, Elektromobilität, Energieabhängigkeit, Finanzkrise, Pandemie, Digitalisierung. Alle hatten frühe Warnungen. Alle wurden ignoriert. Strukturelles Versagen demokratisch-kapitalistischer Systeme.

Great advice. Also something I learned from a @unionofconcernedscientists training is to *not* repost/quote the misinformation in your process of debunking. Give a factual counterpoint and just refer to the misinformation (eg, “I know a lot of rumors are going around, so here are some resources…”)
Hi all -- there's a harmful weather manipulation narrative starting up on X. And dogpiling meterologists. There's also a harmful narrative about emergency response, and sowing hate of FEMA. Our volunteers are working really hard, but we really need help in countering between now and the election.
