Yeah. There seems to be a lot of "clueless". And there always seems to be a perpetual supply of jerks to fill the role of obnoxious...well, nevermind. (They're like lice, more or less. A global problem and just itchy when they become a local one. Barring their transmission of the analogue of typhus, when they are more than an itchy pest, of course.)
The Daughter has a story of some children here (ten, maybe eleven years old). They were at a castle or a church (I don't remember which she said it was) that was ancient, and associated with a particularly noteworthy king. The children had no clue about there having been kings of their own people, other than the ones in London. Scots history is apparently not taught in the schools. (?) The Daughter said she was shocked by how little of their own history the kids knew. Fortunately there seem to be groups here and there who try to keep the culture's history alive.
The old people I have run into with whom the subject has come up in conversation (usually about my ancestry - some of my family were Famine Irish refugees to the USA) are well aware of the Famine in Ireland. They have the Clearances to add to it, and have not seemed terribly fond of the English establishment. Discouragingly, I assume that as the older people die out, unless they've passed along the cultural history they carry, the subsequent generations of kids will become more homogenized in what they do and do not know. Which is a shame, as the Scots seem to be treated, if not quite as obnoxiously as the Irish, definitely as "second class" by some segments of English society. They deserve to know what's behind that. (I've wondered how it is with the Welsh?)
I've no objection to calls for a move to a "British" identity - it's certainly not my place to do so - but the past should never be forgotten. Especially not when it seems there are definite distinctions culturally and in the treatment of the various peoples within the artificially created "nation" of GB historically and contemporaneously. Selective education (leaving out the bad bits) is the same as censorship.
