Relativity

I had a discussion with a friend of mine as to what is considered normal. For some people in some cultures, say being in a plural marriage is normal while here in the US it is not considered the norm and goes against our social mores and whatnot. I like to think I am open-minded but this forum I usually post on: www.omanforum.com a member told me I am not as open minded as I would like to think I am. True. But I would hope I can always learn from others different than myself. I always want to root for the underdog, get their side of the story etc.......
