Is it true that Walt Disney dosen't like Jewish people?

I was watching Family Guy where they have a remote that teleports them to different universes and one was where they were created by Disney and then Mort Goldman who had the star of David walked in, and then other characters attacked him.And then Stewie said oh right this is a Disney universe.Then I told my brother that I don't get it and he said it's because they say that Walt DIsney Was an Anti-Semite.Well he dosen't believe it but is it true?
