Merry Crossmas?

Why do some people insist on shortening Merry Christmas to Merry Xmas?

It really doesn't make sense to shorten Christmas to Xmas. Generally, when you see X used as some form of abbreviation, it's used in road signs. You know... signs that read Deer Crossing, Railroad Crossing, or any other signs that deal with something Crossing are usually shown as Deer Xing, Railroad Xing, or Blah-blah-blah Xing.

One would deduce that X would stand for Cross. Therefore, Merry Xmas would actually be Merry Crossmas.

And yes, I do realize that using X on road signs is more efficient, from an economic standpoint. But with Christmas? I don't think X has any business being in the same vicinity as Christ.

Anyway, instead of writing out the name Jesus or Christ in The Bible, it would make more sense (and save more ink!) to simply substitute His name with an X. The shortest verse in The Bible would be even shorter.

Instead of "Jesus wept," the verse would read "X wept."
