Fair enough. I see it purely that I'm not English or Welsh but that I have to spend a lot of my working life with people from both places. Only a few Welsh to be fair, but still. If England win my pals and colleagues that are English are a nightmare to be around. Just as I would be id Scotland ever f-ing won anything.
I don't like being around fans of other Scottish teams when they do well, and that's not just the Scum - I worked in Edinburgh in the 90s when Hearts won the Cup. I HATED it. Same goes for Sheep fans when I worked in Aberdeen, same goes for the lot of them. I support my teams and that's it.
