If they're putting themselves forward as an expert in Covid19, but they're not right now encouraging or wearing masks themselves indoors at meetings and the like, they're not an expert in Covid19. 1/
If they think there's one blanket solution for controlling Covid19 spread indoors that can be applied to all settings, they're not an expert in Covid19. 2/
If they try to play off one intervention against another, or say this intervention is more important than another intervention, they're not an expert in controlling Covid19. 3/
If they don't think they need to wear a mask at an indoor meeting, and they've kidded themselves into believing that HEPA filtration is enough on its own, when people are literally inhaling each other's breath before it reaches those HEPA filters, they're not an expert in
controlling Covid19. 4/ If they once promoted safe behaviours, but have sacrificed doing so now to "fit in" with those they seek to gain financial benefit from, they're not an expert in controlling Covid19, no matter how much they pretend to be such. 5/5
