And beyond RorHars wellstated point there is a degree to which advanced articles should be allowed to be advanced  I am a trained mathematician but I dont pretend that I should be able to understand this article even when its wellwritten and entirely fleshedout  Class field theory is complicated stuff and people spend years trying to understand even its basics  Its a bit presumptive to come here and pretend like anyone from off the street should be able to read this article once and understand it  I dont think this is an elitist way to think about it  Math is hard sometimes  The most we can hope for is that the lede is sufficiently blue that one could work their way back through the links and try to get some context for understanding this necessarily specialized article
