I couldn't agree more. Even if it were true (which it obviously isn't) and even if we were blameless (which we clearly aren't) it would still be a horribly smug and destructive thing to chant.
As it is, it just embarrassing in the extreme, and at times like that I, a die-hard Oldham fan for 40 years, wonder whether I really belong to this group of people.
That aside a great atmosphere and a team performance to be proud of.
