Symbolic/Symbolism

We have two tags that basically reference the same idea symbolic and symbolism.

I'd say that the former, just for the sake of definition, is closer to how most styles/whatever are tagged.

Now, do we have any use for this tag? I can see this being helpful when paired with commentary or other tags so that you can tell that its meant to be symbolic, but I don't know how many images on danbooru really qualify.

Whether we need the tag could use more debate, but as for which one to use, I've aliased to symbolism because it's a noun.
