Good for them (not sarcastically). My point is that if the experts were wrong then, it’s certainly possible that some of what they are saying now is wrong too, and it should be acceptable to criticize them on YouTube and explore different possibilities and models.

There exist (clearly functional) processes to improve the scientific consensus. The government changed its recommendation. Do you think they were convinced by a YouTube videos or perhaps did some other process cause then to amend their recommendations?

If so, why not steer people toward that process, especially when the harm of wearing a mask is low, while the harm oh reopening the economy due to a lack of understanding the covid dangers is much greater?
