My opinion on extended lockdowns or anything else Covid-related really doesn't have much to do with my opinion that when forming strong opinions on complex subjects, especially ones that differ from consensus of experts, you should have good understanding of the basics of the subject as well as what are the experts basing their opinions on and why. Especially in science where the whole basis of the whole thing is evaluating how well your model performs predicting real world, throwing that all out and feeling things out really isn't as great method as many people seem to think.
