Okay kiddo, so a Chick Tract is a little comic book that tells a story with pictures and words to try and teach you about religion. The stories are usually about people who don't believe in God or are doing things that the author thinks are bad, like magic or having sex before marriage.
The main character in the story usually ends up learning about Jesus and becoming a Christian because they realized they were doing something wrong.
Some people really like these comics because they feel they help spread the word of God, while other people don't like them because they feel they are too pushy or judgmental.
Either way, if you ever come across one of these Chick Tracts, just remember that it's a comic book with a message about religion. You can choose to listen to the message or not, but it's always important to be respectful of other people's beliefs.
