Well, now you guys know what a New York Lib does when he runs out of real arguments. He resorts to name calling. Good work guys! Keep proving me the better man.
STL, I don't see where that changes anything. Plastic in this case is talking about the malleability of the substance used to model and the definition does not apply here. Not foam and plastic like the RTF's are made of. Here's an excerpt from another definition to help you.

plas·tic
adj.

1. Capable of being shaped or formed: plastic material such as clay. See Synonyms at malleable.
2. Relating to or dealing with shaping or modeling: the plastic art of sculpture.

BTW, thanks for proving me right. Again.
