Time to start whacking 

I'm going to go over the entries in the alst section, seeing as how nobody else seems to want to step up to this.

Wagner
This has two citations, both of them problematic. The first actually argues against the point: it says that Hitler liked Wagner, but that nobody else in Germany at the time much cared for him. The second is from a questionable source. Also, its claim that the Ring cycle is "ultranationalistic" is dubious. It's really an article about controversies over playing Wagner in Israel and not a good source about the intereptation of Wagnerian opera.
