To say the Parliament is absolute and arbitrary is a contradiction. Parliament cannot make 2+2 equal 5. Omnipotence cannot do it.
I am not quite following you. However, the reason for the slogan "2+2=V" comes from the protest slogans of the Polish during the communist reign. The protestors stated "2+2=4" to confound the communist who would have thrown people in jail for any other slogan. It was the math/logic of the statement 2+2=4 that was inescapable. Everyone knows 2+2=4. To state such is to say that "it is obvious".
I just modified the slogan to fit with the Article V (convention of the States) of the constitution. "2+2=V" means that there is only one logical direction for patriots to proceed, and that is to an Article V convention - it is obvious.
