What is the spirit of Christmas Charlie Brown?

Ok, first of all, let me start off by saying that I'm not racist and I'm not hating on any religion or anything.
Christmas is a Christian holiday. There is no way around that. Just like Ramadan is an Islamic holiday, just like Hanukkah is a Jewish holiday. We are all agree, right? Then why does Christmas have to turn into this politically correct time of the year? It's not a 'Christmas party' it's a 'Holiday party'. Are there politically correct Mawlid al-Nabi parties that turn into "Every prophet's birthday celebration"? I don't think so. If we are going to be politically correct, then why don't we abolish all religions? No one is allowed to celebrate their respective religion's holdidays because your celebration is going to offend someone who's probably a grinch any other day of the year. Fuck political correctness. If looking at a pine tree decorated with an angel offends you, get a grip. I don't get offended when I see a Star of David and a menorah in window display, or in someone's house. I just say to myself "they are Jewish and they are celebrating their religion's holiday." I don't get all bent out of shape about it. And I have been invited to a Hanukkah/Christmas party. (It was a mixed religion family). Did I get offended? No. The food was great, the music was great, the company was fabulous. Isn't that more important? Shouldn't we look past socially constructed barriers and enjoy the company of our fellow man? The holidays- no matter your religion- should be a time of enjoying the company of friends and family, of giving back the the community/world, and being thankful for what you have.
I'm going to leave you with the lyrics from Happy Christmas by John Lennon. Despite all his flaw, he does know how to express wonderful and timeless optimistic dreams in songs. (If the phrases Happy/Merry Christmas offend you, substitute your religion's holiday's phrase in there).

So this is Christmas
And what have you done
Another year over
And a new one just begun
Ans so this is Christmas
I hope you have fun
The near and the dear one
The old and the young

A very merry Christmas
And a happy New Year
Let's hope it's a good one
Without any fear
And so this is Christmas
For weak and for strong
For rich and the poor ones
The war is so long
And so happy Christmas
For black and for white
For yellow and red ones
Let's stop all the fight
A very merry Christmas
And a happy New Year
Let's hope it's a good one
Without any fear
And so this is Christmas
And what have we done
Another year over
And a new one just begun
Ans so this is Christmas
I hope you have fun
The near and the dear one
The old and the young
A very merry Christmas
And a happy New Year
Let's hope it's a good one
Without any fear
War is over over
If you want it
War is over
Now...
