And beyond RorHar s well stated point there is a degree to which advanced articles should be allowed to be advanced I am a trained mathematician but I don t pretend that I should be able to understand this article even when it s well written and entirely fleshed out Class field theory is complicated stuff and people spend years trying to understand even its basics It s 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 don t 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
