Let's start out with a supposition.
1) Suppose that Murfish is a tool.
2) As an insult, the definition of a tool is...
The word "tool" may be used as an insult, describing someone who is being used by an establishment willingly (as a sycophant), or unwillingly (as one who blindly conforms). Alternatively, the insult "tool" can imply that a person is unable (or unwilling) to form an independent opinion on a given topic.
3) A contradiction occurs because Murfish is not being used by the establishment (WZ).
Evidence: Murfish's voluntary demoddation. Murfish could have continued to work and use up the time that Murfish needs to spend on the important events that are happening this school year, but Murfish decided not to.
Also Murfish is both capable of and willing to make independent opinions on given topics.
Evidence: Murfish disagrees with the statement 'Murfish is a tool'. Thus Murfish is capable of and willing to have original opinions.
4) The evidence contradicts the supposition. Therefore the supposition cannot be true and is in fact false.
Q.E.D.
