I'm sure the Ross County fans weren't offended, but that's not really the point. To take a topical example, if the team formerly known as the Washington Redskins were playing the Chicago Bears and the Bears fans starting chanting "dirty Indian ********" at the Redskins fans, the Redskins fans probably wouldn't be too bothered. But can you imagine being a Native American at the game or watching on TV?
Anti-traveller racism is clearly a problem in the north of Scotland (see below from prominent elected representative and crap linesman, Douglas Ross) and some of our support have played a part in perpetuating that in the past.

The problem is that if it is condoned it inevitably leads to it being viewed as acceptable behaviour amongst a minority of our support and therefore our community in other situations. For example, take this incident where Romanian players were abused purely on the basis of where they were from. The judge didn't view it as banter and rightly so: https://www.pressandjournal.co.uk/fp/news/inverness/835394/caley-thistle-football-fan-banned-from-every-ground-in-the-uk/
One upside of us not having to play County in recent years is that this sort of thing hasn't got an airing. There's plenty of scope to give them stick without resorting to stuff like this. Just focus on cuddly Uncle Roy.
