The Crazies-Ruining It For Everyone

With the holiday season well and over, I have one question for everyone:
Why is it, this time more than any other, everyone has to fight over religious symbols?
The arguments over Christmas Trees continued this year un-abated. I read arguments pro- and con- for public menorahs. The gluttony of the season is always compared to Jesus-I hear the cry "Rmemeber the reason for the season" almost as much as I hear "grab the credit cards".
I don't get it.
It helps that my thoughts on religion are all encompassing. In my humble opinion, one of the greatest gifts God has given us is the numerous ways to pray to Him. We are his children; if God says you are better off a Christian, lo and behold, you are a Christian. If God thinks you make a better Buddhist, lo and behold, you are a Buddhist. All of the world's major religions have the same tenets of one, all powerful God (although some of the religions have lots of helpers), the idea of helping those less fortunate then yourself, and peace on earth. As a bonus, all major religions have their crazies too. Christians get the KKK, Muslims get terrorists, Jews are bombing Arabs over land. But the main point here is that God leads us where we need to go.
A winter holiday has been going on for thousands of years. So the Church borrowed it, re-packaged it, and gave it another name. What this says to me, that on or around Decmeber 25, spend the day the way you want. Go to church and pray for mankind. Give gifts like it is 1999. Go for a hike for thoughtful reflection. Eat a big meal. Or take your family to a truck stop.
Does it matter that we all do it differently? Does it matter that some of us want to remember Jesus, who when all is said and done was a kind and thoughtful man. Does matter that some of us eat till we are sick? Does it matter that some of us light candles instead of plugging in a string of bulbs?
At the time of winter solstice, in the Western Hemispere, I say we do whatever we need to (as long as we respect ourselves and others) to tackle the shortest day of the year and look forward to lengthing days and stop fighting over how we pray. It is driving me crazy! But not terrorist crazy.
