i think having a post edited may be better than having it deleted all together.
Sometimes we arent aware that some words that are acceptable here may be offensive in other parts of the world. I also think that in most cases the OP knows their post is questionable, and sometimes might expect it to be deleted or modified.
I would also have to say that if a moderator changed a post in order to deliberately alter the meaning or the message conveyed within that post, I would find that un-acceptable.
