Penn Jillette discusses the so called attack on Christmas in this holiday speech. In recent years, religious groups have declared that using holiday greetings like 'happy holidays' or 'season's greetings' is part of an attack on Christmas. Jillette strongly disagrees, and discusses why it's okay to use these terms to describe the holidays.
Jillette is an atheist, but that doesn't mean that he's against Christmas. He argues that the holidays are a joyful time for everyone, and that includes people who don't believe in God. Atheists may not celebrate the religious meanings behind the holiday, but that's no reason to exclude them.
Jillette declares that there's nothing wrong with using terms like holidays or seasonal instead of Christmas. He also says it's fine to talk about Jesus or Santa or anything else one believes in, but it's important not to exclude others from enjoyment due to a difference in personal beliefs.
