X'mas really a harmless short-form?

Christmas is just round the corner, did you ever realise that christmas is spelt with the word Christ in it? CHRISTmas. This is because christmas is the day we remember the birth of our Lord Jesus Christ. Whoever created this short form was trying to think of a way to kick Jesus out of Christmas.When someone puts the letter 'x' there replacing the word 'Christ' it's just cancelling Jesus from your christmas... So next time before you say or write it think...should we really place an 'X' there instead of the word 'Christ'?
