Well schools in the UK have just completed Christmas term, and are off for their Christmas holidays. They will have had their Christmas nativities in primary school, their Christmas carol concerts (all schools), their Christmas fairs, their Christmas jumper days, their Christmas dinner and the staff just had their Christmas night out.
The general population has had their work Christmas dos, shared Christmas greetings with their colleagues, gone Christmas shopping, been to Christmas fairs, Christmas markets, bought their Christmas Day outfit, ordered their Christmas dinner etc etc etc.
Most people in the UK are sharing cards with people they know, and are not going to give a Christmas card to someone likely to be offended by it.
May British traditions continue and thrive and not be swallowed up by American ones, like Halloween has been misappropriated!
