Pilots in the US are an extremely conservative bunch. On my pilot group's FB page, the number of times I've read "Let's go Brandon!" in response to this supposed sickout are numerous. Every trip I hear the far-right Breitbart, Newsmax media narrative, and links from similar pseudo news blog sites are posted all the time. It's impossible to fly to SFO or LAX without a comment on homelessness, taxes, liberals, etc. Once, when I happened to be alone on my way to the hotel, a van driver in Trinidad asked my why the pilots are always talking about guns. Many US airline pilots are full-on anti-vax and claim that they'll be fired before being forced to get the vaccine.
