That sounds as if it were written by a lawyer. Scientists don't need to consult a lawyer before they answer a question, philosophers and politicians do. In sworn testimony during the Lewinsky sex scandal Bill Clinton answered a question this way: "It depends upon what the meaning of the word 'is' is. If 'is' means 'is and never has been' that's one thing - if it means 'there is none', that was a completely true statement," >> True, I have only read the first 2 steps (or maybe it was 3, I forget) >> of your Ulster Defense Association proof, but proofs are built on the >> foundation of what comes before, so when one comes upon a ridiculous >> blunder in step 2 (or maybe 3) it would be equally ridiculous to keep >> reading. >> > > > This avoid telling us what you don't understand. > Bruno, if you have something new to say about this "proof" of yours then say it, but don't pretend that 2 years of correspondence and hundreds of posts in which I list things that I didn't understand about the first 3 steps didn't exist. If you can repair the blunders made in the first 3 steps then I'll read step 4, until then doing so would be ridiculous.
