I am a Merry Christmas person. I am a Christian, I am proud of my religion, I beleive in my religion, and I am not forcing my faith on you by saying Merry Christmas. I am just being kind and giving you a warm greeting.
If people don't like what I say, I will smile and give the "doe in the headligths look" and walk away. What I said was not meant to upset anyone, but to be kind and friendly.
I don't get why, as a Christian, I am supposed to be sypmathetic towards others that may not believe the same as me, and keep my greetings to myself. They surely don't keep their beleifs to themselves when they get offended over a simple greeting. JMO
