Happy Fall Feast?

I just happened to catch an episode of Clifford today. They were all celebrating a holiday called "fall feast". It took a few minutes but it finally clicked that they were talking about Thanksgiving. I suppose this is all about the multicultural effort to erase Christopher Columbus and the true history of this country. According to Emily Elizabeth mom fall feast is a time where we all get together to share what we have. I knew Christmas was under attack and about to become officially happy holidays but I had no idea we had erased Thanksgiving to.
