You're right that people don't share the same sets of facts - for example, at least in the US Covid "non-denialists" substantially and consistently overestimate the risk, especially the risk to young people: https://www.brookings.edu/research/how-misinformation-is-dis...
It's far easier to educate someone on correct hospitalization rates and death risks than it is to convince someone that covid is real when they think it's a conspiracy and that vaccines contain poison or something. I don't know why would you want to equate those two things, honestly.
