I was very worried for a month and then regained my critical thinking. A good portion of people are now slaves in the Covid cult.
I think when this all started critical thinking would have led someone to think this was really a bad thing. You could extrapolate a 7% mortality rate from the initial numbers. Once the numbers showed that statistically the COOF is in the same ballpark as a really bad flu season, there was no need to really be any more concerned than normal.
My point is I don't think you ever lost your critical thinking to regain it.
