I'm guessing that Scott doesn't know that the Christmas tree has pagan origins and was adopted later by Christianity.

Their source is ABC news. And Cromwell.
Even that non-scholarly source gives weak support to the claim. Pagans in northern Europe used bits of greenery (not trees) to brighten long, dreary winters. That's just decoration, not pagan ritual. And, again, not a tree.
Oliver Cromwell didn't just ban Christmas trees and new celebrations: he banned Christmas. And Easter. The only holy day was Sunday. And in Cromwell's time, Christmas trees hadn't spread very far from Germany.
My main source is Ronald Hutton's Stations of the Sun: A History of the Ritual Year in Britain. "It was a general custom in pagan Europe to decorate spaces with greenery and flowers for festivals, attested wherever records have survived." Not just at midwinter.
