Is it valuable to learn about other cultures in the classroom?

I that its valuable but we shouldn't learn in the classroom. If people want to learn about other cultures I think that they should look it up on their own time because there is much more important things that we could be learning in English class. If there's a lot of people that want to learn about other cultures they should take geography or start a culture class where that's all you learn. It is valuable to learn about other cultures if you are reading a book like the kite runner though because it gives you background to the book and will help you to understand why characters in the novel act the way they do or do things the way they do. So all together I guess it just really matters why you're learning about the cultures.
