This is a very specific and nasty example of a trend I've witnessed becoming common on a whole bunch of issues: climate, health, economy, pedophilia, etc etc.
Useful idiots online are spreading "I'm just asking questions" garbage about "pizza gate" and the "covid hoax" and the "climate hoax" etc etc, and anyone who has to deal with this just gets beaten down and withdraws their participation.
I don't even know who the hell could possibly benefit from damaging the BOM/CSIRO, without some multi-party and honestly contradictory conspiracy of china + russia + resource companies.
