Offering your personal (re-)definition of basic concepts in mathematics (I snipped your redefinition of the concept of graphs for brevity) is a counter-productive response. If we all began to re-define common concepts, I might label you "intelligent" and my personal definition of that term might be http://c2.com/cgi/wiki?TrollDefinition.
If you're interested in finding out what a "binary relation" really is,
Google is your friend:
