Sorry, Rabbi, but the Menorah, like the Cross or a Nativity Scene, is an overtly religious symbol and Christmas tress are not.
If you want the Jewish equivalent of Christmas trees put up at the airport, you are going to have to settle for giant dreidels.
I would agree, but the courts have consistantly disagreed with that position for decades. Both have religious and secular characteristics, I admit the secular for the Menorah (and Creche) is beyond me.
The dreidel is sometimes suggested. Personally I think it would be a poor choice, given it's origin in religious persecution. In at least one case, Allegheny I believe, the court rejected it because a large dreidel would look "silly". Go figure.
Some christian was complaining when a shopowner in a small town bought "holiday" flags for the citiy to put up on the light poles. The complaint was that the flags were tapered, so they looked like Draedals, the flags were blue with white snowflakes that looked like a jewish flag, and a couple of the snowflakes were shaped like the Star of David.
We need to celebrate, and allow the celebration, of positive things, not be at each other's throats. MORE speech, not less.
