>The way Wikipedia is supposed to work is, they have to find sources for 2+2=4 or 5.

>Albert Einstein explaining (as a primary source) how 2+2=4
His explaination has other credible sources cited (that prove that 2+2=4, so this isn't WP:OR).
None of that matters though, because the other editors will just claim concensus, and that the page has had 2+2=5 for years, so they'll just revert to the incorrect, narrative safe version the page has always been.
