This is a joyful time of year for many different groups:  am I offended if they share their joy with me?  Not at all!  So in turn, I hope I convey only good will when I say - Merry Christmas to all , and to all, Happy New Year.

How far can political correctness go?  Consider the department store in England which was told that it would not be allowed to advertise for a man to be Father Christmas in their store. To advertise for a single sex meant justifying in writing the reasons for such blatant prejudice. The owner, Bruce Robinson complied with the directive. He wrote:

"The person, if female, should, therefore, have a) a deep voice; b) whiskers; c) a big belly; and d) no readily discernible bosom.

"My only concern is that if our choice is limited to such a candidate, I fear for our children, who will doubtless be terrified."
