Let me explain this in crayon, since apparently you learned your history from Dickens' books rather than reality or basic logic: 1) When you say "the Roman Census", *which one*? There's a well documented census in 6 AD, but that's much too late. There's some speculation that Quirinius may have been in charge of the area twice and that he conducted a census the first time around as well. That would at least plausibly be far enough back, though hard evidence for it is thin. 2) When you say "the date, the month, the season are very well known" you're either lying or retarded. No one has proof of this. It's mostly taking Luke's word for it that it happened at all. And Luke didnt bother to write down an exact date because it's irrelevant to everyone but Pagans and Dickens. 3) Conducting a census in the region in late December is highly implausible. The travel conditions are lousy due to the chill and tendency towards rain or occasional snow. 4) Shepherds dont hang out with their flocks in the fields in December in the region. There isnt going to be jack all for pasturage until March or April. Also, did I mention the chill and precipitation? Poor conditions to keep sheep in for no benefit. 5) Stop reading Dickens if you think he's a historian. Next he'll have you believing that there were *three* magi who showed up on xmas, rather than *indeterminate number* who showed up quite awhile later because traveling from probably-Persia takes awhile.
