We are a world wide organization since 2002 (you may have seen the patches). Regardless of faith human beings seem to be wired (whether through upbringing, genetics or marketing) for celebrations at the end of the year.
This is not political correctness, nor is it an invitation to get into a debate about religion. You can choose to be myopic and live in your own little world, but I would prefer to include rather than exclude and wish you a happy _insert your holiday here_.
If you're Christian, Merry Christmas
If you're Jewish, Happy Hanukkah
If you're Buddhist, Happy Buddha Enlightenment Day
If you're African-American, Happy Kwanzaa
If you're Hindu, Happy Pancha Ganapati
If you're Seinfeldian, Happy Festivus
If I left out your holiday (and a quick search of wikipedia tells me that I may have), see above.
