There are Christian traditions and there are non-Christian ones.
Being a world of many cultures allows us to have all of them.
If I see a Menorah in a window at Hanukkah I don’t call them holiday lights.
In 2001 The Taliban leaders issued a religious edict deeming two of the World’s tallest Buddha Statues, which are carved into a mountain, as non-Islamic and ordered their destruction.
Although I am not Buddhist I see this as a great loss of a traditional symbol, in much the same way I might morn the demise of the Christmas tree.
I think it is more honourable to say your religion doesn’t offend me, then ban it from being seen or spoken.
To Christians this is to be a time of Joy, let them have their joy at Christmas.
