Kanye West's anti-Semitic tweets have been in the news this year.
Natan Levy, a professional mixed martial artist in the UFC lightweight division, has challenged the rapper.
Levy, a Jewish, called out Ye after a victory against Valdez at UFC Orlando.
"I think life is essentially too short to hate, so to these hateful people it sucks for you, I feel sorry for you, " he said.
Kanye West, if you have an issue with me personally or my people, come see me, brother, he said.
Twitter users suspended West after he praised Adolf Hitler in an interview.
In recent months, Ye has made several anti-Semitic comments and threatened tweets.
