Zackass: an internet troll whose opinions are always more equal than others; one who will put you down because he has 'served his country' and believes that you have not; one who will never admit he is wrong, despite overwhelming evidence to the contrary
just because your opinion differs from mine does not make it better, or more valid; stop being a Zackass
