All any of you achieve with the "meh they don't really matter" rhetoric is to show that it does matter enough to you for you to make an effort to try and put them down. If it really was a nothing game then you wouldn't have to say anything at all.
That's bollocks. Saying "I honestly don't give a shit about them" is not a put down. I'd say it about Cheltenham and I'd say it about Doncaster.
