Zerohedge was kicked off Twitter for suggesting that the Wuhan Institute of Virology was a likely candidate for the origin.
We're seeing that Fauci & Ecohealth co-ordinated the paper to "debunk" the lab leak theory and now the lab leak is looking to be the most likely culprit (it is not without precedent, the 1977 Russian Flu turned out to be a lab leak from gain-on-function research).
Ivermectin, was another. Complete with "horse de-wormer" smears and deplatforming campaigns all over the place.
If you don't know of any instances where this has happened, you either did a masterful job tuning it all out, or still believe 99% of the b/s.
