Completely and utterly disagree. It's kids education that needs saving, not xmas. The NHS, the food factory workers.
God won't care if you don't celebrate his sons birthday in the usual way this year.
If you are even contemplating isolating for two weeks before xmas to see family (maybe an exception for very elderly people clearly facing their last xmas) then you have no bloody idea how lucky you are this year. Some of us don't have that choice schools or not.
