Dour atheistic Calvinists?

I have seen the annual recurrence of the debates within Humanism over the celebration of Christmas in the Think Humanism online discussion forum. Some, rather odd people in my opinion, are vexed over the issue of whether joining in with Christmas is a sell out to the still dominant religion that they have chosen to turn their back on. I lived in Edinburgh during my time at university and the Scots make a bigger deal of New Year (Hogmanay) than Christmas - indeed the English celebrations have a definite Scottish flavour . I saw in the New Year eating haggis, dancing to I would walk 500 miles and Donald where’s your troosers, not to mention the obligatory rendition of Auld Lang Syne, what’s more Scottish than that? Does joining in with Hogmanay suggest I am impersonating a Scotsman? Perhaps if I donned a kilt (as some do in England) I would be going too far. I think that there is an irony in that the reason the Scots focus on Hogmanay for their drunken revelries rather than Christmas is not that they are less religious (I think they are more so - or at least they were) but that the pious and puritan Christians of 16th century Scotland effectively banned the traditional Christmas to impose a more Christian version of it. The truth is that the cultural milieu we find ourselves in is not of our making but traditions gradually change and eventually new traditions will be invented that future generations will imagine to have existed since time immemorial. We all play our part in the formation of that future culture but I doubt if many of us will be around to see it arrive. Our Christmas probably owes more to Prince Albert and Charles Dickens than to the synoptic gospels and if you want to abolish it, perhaps you have more in common with those dour Scottish Calvinists than with the spirit of Humanism.
