If I understand you correctly, you are using Covid-19 as a means to justify any position (or broad classes of them) which is convenient to you. I say this because you're using it in a broad way, and making an appeal to specific prejudices.
I am saying that if you want to justify saying that a particular statistical anomaly that occurred during the 2020-2023 timeframe is not wholly or nearly wholly caused by the pandemic and its direct and indirect effects, you better have some damn good data to prove it.
