Because this particular example of wrongthink was given a literal gold badge of approval from Twitter. Because that badge of approval caused this wrongthink to be seen by a great many people. Because Twitter has been caught red handed lying about its moderation policies to defraud advertisers and this is a blatant example of that fraud. Because Twitter's owner has himself espoused neo-Nazi wrongthink by praising Hitler, claiming Jews are conspiring to destroy white America, and saying he has no sympathy for Jews who face antisemitism. Take your pick.
