So you're completely ignoring the "this" in "this Christmas heralds a time to celebrate the good news of a new King"
And while I'm familiar with that little diddy, I don't recall any of these actors in question ever used that phrase in a public message.
Now had that said "Christmas heralds a time to celebrate the good news of a new King", you know the version you're reading, than I would agree. But they did not, they said THIS Christmas, as if this one is different that the others. You can choose to ignore it if you like, Trump supporters are perfecting this phenomenon of morphing right along with Trump.
