Yes there was, but it was mostly about removing the pagan Winter-solstice traditions that crept into the holiday, which is why Christmas was banned by Christians in various Christian countries a few centuries ago(as described by previous posters). It was never that big of a holiday to begin with, until recently.
This recent "War on Christmas" BS, on the other hand, is a political weapon obnoxious right-wing Christians use to rally their storm-troopers to bully the non-Christians into submission. The political-economic aspects seem to be far more important to the hate-mongers than preserving the actual holiness of the holiday; hence their extreme anger over store employees saying "Happy Holidays" to customers instead of "Merry Christmas", while there is never any anger over buying countless goods made in atheistic China. There's no anger over the commercial nature of it from the Reich-wing Christian blowhards at all.
They similarly cry "persecution" if they can't use public property to promote paganism, uh I mean idolatry, oops I mean their "Christianity", while excluding all other religions, which is unconstitutional. It would be great if these Reich-wing Christians read their Bibles once in a while.
It's obvious who their real master is.
