Re: Alexander Marcus/John Paxton connection?
I think Marcus could be said to be xenophobic to some degree, seeing as how he evidently strongly dislikes major alien powers, notably the Klingons, and seeks to destroy/subjugate them, making the Federation more totalitarian.
While there was indeed a certain amount of speculation about a possible Paxton connection from the time Weller's casting was announced, I don't think such a link is really necessary in order for Marcus to exhibit any or all of the qualities you list.
