You’ll NEVER be convinced on anything mate from what I make of you.
Except of course everything you are told and told to do without question by any authoritative or official body
Difference in your weak example is that 2 plus 2 actually does make 4 as a fact,.anything you have been told by a teacher whether it be maths history, or geography will be sure as hell FACT.
The stuff where you are going wrong is readily believing theories and opinions without question (evidently) especially if there is a strong whiff of hidden agenda…not to mention obeying plain ridiculous rules that are a bit ott… because they come from the same sources.
Hope that helps and clarifies…you’re welcome
