When will we get it through your thick skull that Chipmunk is not equal to Rodent?
You're saying that a subset of a set is equal to the entirety of the set, which is incorrect inherently.
When you say Chipmunk = Rodent, you're claiming two things:
1. Every single Chipmunk is a Rodent (that is true)
2. Every single Rodent is a Chipmunk (that is false)
You have to fit both conditions for you to even be able to CONSIDER that your statement is true.
