If we claim we speak truthfully, then that we perform an act of testimony.
If we are both trying to find the truth, then we engage in an act of discourse.
If we are both trying to persuade and inform a jury(audience), then we participate in a debate.
But if you are trying to engage in deceit for the purpose of theft (free riding) then you are a defendant and I am a prosecutor.
I AM A PROSECUTOR
That is why I appear and am hostile. If you are a parasite, then I am a prosecutor. And I want to build an army of prosecutors the way the Jesuits did.
Except this time, we will prosecute liars.
