The wiki you linked opens with a claim that is provably false.
> "It's okay to be white" (IOTBW) is a slogan which originated as part of an organized alt-right trolling campaign on the website 4chan's discussion board /pol/ in 2017.

When I checked a few of those results, it was just showing that Google's date parsers were either wrong (there's a neo-Nazi band's song denying the holocaust listed as 2001 but the actual page is from 2021) or news stories which predate 2017 but do not mention that phrase anywhere except in something like a “top news” box which happened to feature a story about Scott Adams when Google most recently crawled that page. Twitter appears to have a similar issue with things like pinned or related tweets where the date Google shows in their snippet doesn't block to a tweet with that phrase.
The other thing to remember is that there's a difference between whether anyone in human history has ever combined 5 words together before and the organized campaign promoting that as a catch-phrase aiming to boost white supremacy. If we find a few neo-Nazis using that phrase before 2017, it doesn't meaningfully change the idea that the reason almost everyone else has heard of it is due to the /pol/ campaign — to call that into question you'd want to see if there was non-racist use prior to that date.
