When you are removing large chunks of longstanding text and are not merging them into other articles please move the cut text to the talk page See Wikipedia Editing policy On editing styles Whatever you do try to preserve information If in your considered judgment a page simply needs to be rewritten or changed substantially go ahead and do that But preserve any old contents you think might have some discussion value on the talk page along with a comment about why you made the change Even if you delete something that s just plain wrong odds are that it got there because someone believed it was true so preserve a comment that it is in fact wrong to inform later editors I am quite sure that what is being removed is not just plain wrong and with the rejuggling of sections it is hard to see what exactly is being removed
