What's interesting about this, and I'm surprised no one brought it up, is that my argument's validity depends on logic which I'm trying to show is independent of truth. I use logic to argue that there is no truth in logic. So is "there is no truth in logic" true??

An interesting quote:

"The dominant tendency, however, to treat as equal what is merely similar – an illogical tendency, for nothing is really equal – is what first created any basis for logic." -- Nietzsche.

There are a few binary logics out there.

Some of those are not binary.

Well, in classical logic, that tendency isn't present. But there is a notion of "equivalence" among logic formulas (statements) which is mutual implication.
