I consider myself blue collar, atleast from that type of background and thats unfortunate for meh, so the next best thing is to fight against it . Just sit back and enjoy the chess match if you're not familiar with the fighters. If you completely must 'root' for someone then wait till you've seen a little bit of the fight. Chris Rock said it best "Anyone who makes up their mind before they hear the issue is a F****** fool", in boxing it's before you 'see' the issue.
