Yep - he's shifting the narrative and pointing the way for Bernie Bros to be able to discuss openly their health concerns and experienced from vax and boosts. Imagine being a young techie who's always been a Good Kid who drinks deeply whatever Koolaid a person in a position of authority tells them to drink. They've always done as told. But now their fiancee has a cardiac issues at 28 just after getting boosted. Or the Bernie Bro himself has a cardiac issues, and young vaxxed athletes are dropping like flies. You'd never go to a site like GAW for info (conspiracy theory branding). You might maybe trust a reddit thread? But Elon discussing it on twitter makes talking about it and learning about it okay. Toss in some Joe Rogen Experience? These guys have to be able to allay their concerns and fears somehow. Good on ya, Elon!
