Welcome to the board.
I'll ask just one question about your comments about Christmas - "What doesn't have pagan roots?"
Honestly, there are few things (IMHO) that *don't* have pagan roots. Every society is influenced very much by its pagan past. Just look at celtic symbols (seen everywhere in the UK), our calendar (pagan roots), "traditions" such as wearing a white bridal gown and having rings on our fingers as a symbol of marriage (again pagan), Even the way Christians take bread and wine is strikingly similar to older pagan customs of sharing bread and wine as body of God.
Even the society themselves have published articles which say that to look for the pagan roots in everything is not worthwhile. The trouble is, they seem to want to choose which things it is OK for you to do. This is simply not allowing you to have your own Christian conscience (can you see the pattern of how they tell you how to live your life? this is about control, remember).
Given that there are so many pagan influences, many Christians decided to change the ancient pagan festivals and make them Christian. This isn't wrong in my opinion. They are making it about Jesus, who according to the bible replaced the older pagan ways. Just as he replaced the old mosaic law (which noone says is "bad" they just say its "old and out of date now") Christians replaced festivals like Yule with Christmas. Isn't that a good thing from a Christian standpoint?
As I said, if you were going to take out all of the pagan stuff then you'd find it near on impossible to live any sort of normal life! You'd be a hermit on some remote island if you wanted to avoid EVERYTHING that has pagan roots. Some say that the bible itself was greatly influenced by the pagan stories which existed at the time.
Just read read read as much as you can about it all. Then you'll start to realise that there really isn't an "us or them" thing going on with God. At least that is what I think!
