I taught secondary for decades in different schools, and honestly I don't ever remember singing carols ever
Same here. Secondary ad 6th Form in very mixed schoolsin a region that pioneeered comprehensive education.
So I think it depends very much on the kind of school you went to, or taught at. My GCs and nephews and nieces all go to very 'posh' schools and all sang carols at Christmas, but not in the 6th Form.
I so love singing, but why does it have to be carols. There is excellent and rousing, moving music, classical or not, from the UK and all over the world, that we can enjoy and share, irrespective of faith or not. As a Humanist, I strongly believe that faith is a personal matter, which those who want to can enjoy freely with each other- but should not be imposed on to others, music included. I left 2 choirs because I felt uncomfotable with the very religious lyrics.
