It generally annoys me when I hear people making comparisons between Jesus and other mythical deities, because most of the time, they make false analogies. The most common ones are what people learned from movies like Zeitgeist (which is horrible), and they make bold claims like "The Jesus story was copied directly from pagan religions!" and "All of these gods (10s or 100s of them) were born on December 25th of a virgin and when they died rose 3 days later!"
My biggest gripe with these faux arguments is that there ARE legitimate comparisons to be made. There are quite a number of dying and rising gods in ancient religions. There are a number of mythical man-god figures who were said to have been fathered by gods. There are also other figures who are ascribed many of the same kinds of miracles that Jesus did. These are the comparisons that should be made, and are made by people who know what's what. It isn't a black and white issue and the stories are not identical. I really wish people would stop speaking out their ass and treating movies like Zeitgeist and Religious as scholarly sources.
