Great post, seems we've got another washed up celebrity with more mouth then sense trying to owe himself to christianity.
So Cameron doesn't want atheists celebrating Saturnalia then? I'll tell you what I'll do mr cameron, I'll celebrating it, show all the fun I have with my family for christmas, take a load of photos of the meal and the presents and watching christmas movies and getting drunk.. and then i'll take a photo of the shit I take the day after from all the turkey and trimmings, and post it to your twitter account ^^
Really though, if this douche goes ahead with making a movie whos primary aim is to attack atheists and try to create the message that 'Christmas isn't for you!' if he wants to be separatist, by all means let him, it'll just be more fuel for roasting these sand worshipers.
You even have pope Francis having yelled out for atheists to join in celebrating christmas with faith groups. Not that I give a shit what the head of an order that hordes riches from the poor says.
