Kanye had a lot of antisemitic episodes before the AJ interview.
In the song "Flashing Lights" he says he hates the paparazzi more than the nazis. Which many saw as comedic exaggeration for the sake of an easy rhyme way back when it came out, but in hindsight it's a big red flag about how he sees the media (including the celeb-stalking media) as Jewish-owned, and how he hates the (Jewish) media more than the killers of Jews.
In his album Life of Pablo he praises homophobic and antisemitic NOI leader Louis Farrakhan on a couple of occasions.
He also has this antisemitic lyric from the song Saint Pablo off of Life of Pablo:
Brother Don Muhammad told the minister about the presentation
He sat back and smiled
Black on black lies is worse than black on black crime
The Jews share their truth on how to make a dime
These were all invisible to people for some reason. It took him going on Alex Jones and praising Hitler before people noticed.
because he always has the most dogshit lib takes that are so mind bendingly reactionary they have to be reposted as cringe in the dunk tank. Every one of his tweets is a work of art in how wrong it manages to be.
