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

Personally, I really don't think that is it valuable to learn about other cultures in the classroom.. The topic doesn't really interest me and I have a hard time focusing with it.. I think other cultures become more interesting as we get older but right now its kind of boring. I think if people wanted to learn about other cultures there should be other ways instead of the 3C unit and that in high school we should be learning about something else.
