I'm not sure what your point is. Canaanite religion used trees as a symbol of their deities and a site for fertility rites. So did pagan Germanic religion, from which we draw the tradition of the Christmas tree. I'm sympathetic with those who don't have Christmas trees because of this connection; we didn't have one, the year I read "The Iron Hand of Mars," and the fact the we get one as a rule is my German husband's decision.
However, unless we're performing Nordic fertility rites around the Christmas tree, it's just a nuisance, not an idol.
Relax, the Germans worshipped the Oak tree (like the Celts). According to legend, St. Boniface instituted the idea of using a fir tree as "the Christ Child's tree" because when he cut down a sacred oak tree (just to show the Germans that he wouldn't be struck dead when he did it) the oak tree crushed all the trees it fell on except a little fir tree. St. Boniface seized the moment and declared that "the Christ Child's tree."
