Hi and welcome. I have reverted all of your changes, which simply remove pop culture/fiction from many articles. Some of the elements you have removed should be removed, and others shouldn't. For example, Raison d'être is a disambiguation page, and is intended to list items with similar names.
If you wish to continue culling the irrelevant fiction/pop culture from Wikipedia, "In popular culture" articles is an essay that may interest you. If you actively copy-edit a article, you will have more success in removing irrelevant elements. If you have no interest in the articles beyond removing everything regarding pop culture/fiction, you will find that editors here dont trust you to have been careful in your selection of what to cull. So, I recommend that you focus on a few articles and demonstrate your ability to treat fiction/pop culture appropriately. John Vandenberg (chat) 03:44, 10 September 2009 (UTC)
