I'm not a Christian. I don't believe Jesus to be divine. I have no problem with the ideas of gods before Jesus. I don't even believe he was resurrected. I believe it was a story created after the fact. However, I do object to misinformation being spread.
Also, just because another person was resurrected is meaningless. Lazareth was resurrected in the Biblical story. It does not suggest that Lazreth's resurrection has anything to do with that of Jesus's. Also, just because resurrection happens, does not mean that it was a blood sacrifice. More so, the form of resurrection is different.
There is no way that the Jesus resurrection was based off of Osiris resurrection though. They aren't even close to the same. Osiris was dismembered and magically put back together. Not even in the same ball park as Jesus.
Also, as I already said, many of the examples you gave were not resurrected. And it does matter because you are trying to claim something that is false.
