Science....unlike religious dogma....is ever-changing based on new information at hand. It's actually a sign of higher intelligence to periodically change your opinion on matters with the acquisition of new data.
I am comfortable with my opinion on masking. I am more conservative with my opinion on mandatory Covid vaccines using MRNA. That said, the data still favors it just not as much as advertised....Hence, my change of opinion regarding the mandates.
There no science based argument that ever existed for masking or mRNA shots. None at all.
