I think I should be able to say Merry Christmas without fear of persecution. Sure, radio stations, and TV stations, and TV programs, stick with Happy Holidays as they generally represent a number of people with a number of religious beliefs, but *I* have my own religious belief, and that is in Chritsmas.
I don’t believe that wishing someone a Merry Christmas is offensive. It’s not me shoving my religion down your throat. It’s me saying this is my religion, I wish you well. I would not be offended to be wished a Happy Hanukkah or a Happy Kwanzaa (Kwanzaa isn’t even a religious holiday…). It just seems these days that people are so scared to offend people because there are some idiots out there who go out of their way to be offended by everything they possibly can.
