Merry Christmas
If you are rightly concerned about the obvious intention to get rid of the old Christmas greeting of Merry Christmas and the deliberate omission on the company products, websites and Christmas greetings activities — the solution is obvious!!!
Make a list of all the companies and organizations that deliberately omit the Merry Christmas and vow never do business or have any dealings with these people on your list.
You will feel much better and if enough people apply this personal boycott these people will quickly change their behaviour.
Even if they do, ask yourself if these people are the people you want to do business with or associate with in the future.
