Should we bother? Roseanne Barr is a deranged conspiracy theorist who has represented both leftwing-oriented and, more recently, rightwing-oriented nonsense: at one point, she endorsed dingbat loon Cynthia McKinney; more recently, she’s been a vocal defender of the Trump. Throughout her career, she has promoteda number of conspiracy theories– e.g. about Parkland shooting survivor David Hogg, the murder of Seth Rich, George Soros (but of course), chemtrails and COVID-19 (a conspiracy to get rid of baby boomers) – and possibly invented some of her own, including conspiracy theories about why she is promoting such stuff. In particular, she started promotingQAnon conspiracy theories before it was mainstream.
Diagnosis: Bah. Total bullshit, the whole character. Just forget her, shall we?
