Hang on... I'm confused... the only reason not to wear 'colours' (and not necessarily the official Club Shop £50+ per shirt merch) is to have a pre-match tear up dahn the 'Igh Road, and not be picked up by the Old Bill Filth... is that what people are alluding to, when they say on;y kids wear colours??
If we're all so allergic to wearing white, then we should all turn up wearing Red... no one would ever suspect anything then... but of course, that would cause a meltdown, 'cos we all know colours DO matter... it's what our club, what every club is about. Why else did the whole of Cardiff go epileptic for a season and a half when 'told' to wear red??
You don't have to buy the kit... but surely upon surely, wearing an item of white (or navy) clothing for the day, to show your support for the CLUB, isn't beyond most people... even the Johnny-come-lately-hipsters amongst you!
