Anyone who is sympathetic to the aims of the Meritocracy Party - and that means that you object to all those who use nepotism and cronyism to rig the system in their favour - is free to promote the Meritocracy Party in whatever way they see fit. You do not need to seek any permission.
The Meritocracy Party objects in particular to the the "Superclass" of 6,000 individuals, many of them billionaires, who run the world as their personal fiefdom (see Superclass: The Global Power Elite and the World They Are Making by David Rothkopf). These individuals use nothing but cronyism and nepotism to advance their goals. They have no interest in you, no interest in justice, and the last thing they would ever advocate is meritocracy because that is the one political principle that would destroy their insidious cartels.
