I understand what you're saying.
My covid case involved me being achy and having a low grade fever for 2 days, losing all taste and smell for about 2 weeks, and some light sensitivity and headaches for 2 days.
Now, i've never had anything cause me to lose sense of taste and smell, so do I believe SARS-COV2 exists, yes, along with SARS-COV and all coronaviruses.
Do I believe in a plot, false narrative, testing issues, etc? Yes...and more.
