Christmas Should protestant Christians Celebrate?

So on my Facebook a women has been reaming me saying real Christians should not celebrate it because it is a pagan ritual infused with RCC harlotry etc etc. She sounded like I used to whenever I got into it with some of you all . Long story short, sure Christmas is by historical nature a pagan/RCC holiday. But since I doubt any of us worship the tree or the Yule log I serious question this lady's sanity. I think she just hates Catholics and thinks here personal views are gospel. She tried to use scripture but I showed her how she was doing so out of context etc etc.

So my question is should we celebrate yes or no and why yo think that?
