Please stop removing invalid tags according to your own whims while this discussion is ongoing, or risk a short block per Tardis:Do not disrupt this wiki to prove a point.
(Without responding to everything you have to say, Global Conspiracy?, I do agree, should be considered a valid source. As I said on the talk page. The invalid tag was added by someone who'd never seen it, because someone else added the parodies category. It will likely be switched over. But that's just it -- we deal with these on a case-by-case basis.)
