Merry Christmas or Happy Holidays?

How should a Christian respond to "Happy Holidays". Should we respond with Merry Christmas and remind them the "reason for the season" that unto us this day a Saviour is born and He is Jesus Christ the Lord?

Do we boycott retailers that remove Christmas from their stores completely? Groups such as Focus on the Family, Liberty Counsel and the American Family Institute create lists of retailers that support or market Christmas, "Good" or "Nice" and those that have no mention of Christmas, "Bad" or "Naughty".

Some of the "Nice" retailers that mention Christmas in stores or in advertising are; Best Buy, Cabellas, JC Pennys, Kohls, Menards.

Some on the "Naughty" list that refuse to mention Christmas; Circuit City, Costco, Disney, Gap, Nordstrom.

Should we even care if these Non-Christian companies try and appease us by saying "Merry Christmas"? After all, aren't they just greedy and after the all mighty dollar?

Please post your thoughts.

Here is short song by a Christian Band that sums up their beliefs.
