I had a friend in Carmarthen who was a jack . His brother was too. We were having a conversation about going to a wales game or something about the internationals and I remember his brother feeling a bit peturbed by this and saying "Aren't we supposed to support england?"..... The comment made me think that there must be an undercurrent of weird british/english nationalism going on at swansea...he said it as if it were obvious that a swansea fan should support england. This was about three decades ago.

They remind me of the people in American History X ......... dinsenfranchised and dangerously lacking in culture.

At least that's one element. The other element are welsh(ish) speaking , rugby (sport) fans who are attracted by the "product". I have friends who belong to this category too.

It's a weird mix.
