So I'm one of those people who get really bugged when people say Xmas. "Merry Xmas!"..drives me crazy because I feel like people who say this are taking the most important part of the holiday, Christ's birth, out of the holiday. I recently just learned that X is actually the ancient symbol of Christ. So, no matter how you say it, "Merry Christmas!", "Merry Xmas" "Happy Christmas Ron" or "Happy Christmas Harry" you're paying tribute to Jesus, the most important part of the holiday.
