Joe wasn’t defending Kanye West’s song, he was defending freedom of speech. If you listen to the full segment, Joe points out the irony: Kanye rants against Jewish people, yet likely still buys diamond-encrusted jewelry from them. In America, we have the First Amendment, and defining hate speech is complicated. Joe wasn’t promoting the song; he understands that when something is banned, public curiosity increases. By allowing Kanye to broadcast his music, people can judge for themselves just how vile and disturbing it really is.
