::1) No-one 'deleted' the article, it was redirected. Redirection is not deletion as it can be undone.  
 ::2)Your undoing of it was not my main problem, but rather that you (unlike the person who redirected it) made no attempt to explain your actions on the talk page, or to see if anyone agreed with you. Further you called them a vandal - hardly assume good faith. 
 ::3)There was no 'merge notice' as no merger was being proposed - a redirect had been proposed and no-one had objected. Now that someone has (and, objecting is a resonable thing) there should now be a discussion and not an edit war or a slagging match.    
 ::The content of the article can be discussed on the talk page not here.
