Re: [Rails] Implementing a tagging system in Rails

I don't think this is true. According to the Rails API, this is what collection.delete does with a has_and_belongs_to_many association:

"Removes one or more objects from the collection by removing their associations from the join table. This does not destroy the objects."

I went ahead and tested this out just to make sure and sure enough, only the association was deleted when I called save, not the tag itself.
