I'm sorry the ENTIRE premis of Christianity is about how Jesus died on a cross for your sins and then rose from the dead. That's the "good news" as Christians say, that should be spread, belief in that process is what gets you into heaven, there is no other way to salvation, according to most Christians. So, yeah, the fact that Christianity "incorporated" it from other sources is sort of important.
You were offended before I even said "resurrection thing" You were offended on my first post on that particular topic spare me the false outrage. You were offended that I brought it up, not because of the phrase I used in the second post on the issue.
