I understand you believe you are practicing inclusiveness by wishing us "infidel atheists" the best of the season and speculating on what we celebrate in December when you are enthusing over the birth of Christ.
Well, in all good cheer, let me wish you in return a Happy Winter Solstice!
You do realize you sound like a fool when you assume the holiday you borrowed from centuries of nature-worshipping pagans belongs to you and you alone?
You, my friend, are celebrating Winter Solstice whatever you like to tell yourself. If you doubt this, have a closer look at the customs that you probably think are Christian.
