Actually ALL of those things have had quite a bit to do with Christianity...for the last few hundred years or so and more.
They certainly have not—since Europe became (culturally) Christian, over 1,000 years ago—had anything at all to do with paganism.
Ancient pagan religions, as with current day animistic religions, as found in Africa, New Guinea, and other places, spiritualized (demonized) virtually everything, meaning no created thing can be used that didn’t, at one time or place or another, have some pagan/occultic association with it. The important thing is, does it have a pagan association in how it is recognized and used now—or has God’s power in our culture overcome pagan associations and redeemed things in creation, once used by powers of darkness?
Last I checked, eggs, rabbits, trees, reindeer, snowmen, mistletoe, Christmas wreaths, holly, eggnog, Christmas stockings, and Christmas presents....and even pumpkins....are God’s creation and dominion, and not demonically controlled things.
wow, you are delusional.
all those things are pure paganism.
