Xmas.... What's in a name?

This abbreviation for Christmas is of Greek origin. The word for Christ in Greek is Xristos. During the 16th century, Europeans began using the first initial of Christ's name, "X" in place of the word Christ in Christmas as a shorthand form of the word. Although the early Christians understood that X stood for Christ's name, later Christians who did not understand the Greek language mistook "Xmas" as a sign of disrespect.

A large number of businesses have taken Christ out of Christmas this year claiming its less offensive to non believers in Christ.

Question: Should we start using "Xmas" for the holiday season? (justify your answer)
