I'm not sure that this is actually a real term, simply an adjective describing a noun. (I also find it interesting to note that when typing "liberal gloss" into Yahoo the very first entry is from socialistworker.org).
That being said, I tried to salvage this article as best as I can. The origonal author has been warned numerous times about writing unsourced polemical attacks (which are likely parody at any rate). HelpJazz 21:58, 10 October 2007 (EDT)
