I've received and read a lot of holiday greetings this year with apologies and/or caveats attached. I have seen things like, "Merry Christmas (if you celebrate)" and "If Merry Christmas is too offensive, Happy Holidays". I'm sure a lot of people, aren't even mentioning the "C" word or extending holiday greetings at all for fear of offending someone.
I know that if someone told me "Happy Hannukah", I would think, "How sweet." Or, "Merry Kwanzaa", I would say, "How nice. Thank you." I am neither black nor Jewish but I would appreciate the thought that someone wished me well especially during a time of year that was spiritually important to them.
Bring on your well wishes during your Winter Solstice, Chinese New Year and all of your Muslim holidays. I accept blessings in any form you want to give them.
Merry Christmas to all, and I do mean all, of you!
