How is it at all vague? A plethora of god-figures were killed and resurrected, and not as some cycle.
Not really. You claimed that a plethora of god-figures did such; however, even the list you provided showed something different. Dionysus, again, was never resurrected, but was reborn. There is a difference here. I do not believe Krishna was said to have been resurrected either (well not until quite later on).
For Baal, it was a death and rebirth cycle. As in it was an annual thing. This is true for Ishtar as well. I don't know about the others you listed, but when we see the majority of those that you list not being resurrected, the rest come into question as well.
More so, Jesus was not thought of as being unique in being resurrected. If we look at Paul, the earliest source for Jesus, we see Jesus only being the beginning of the general resurrection. Again, that is quite different from those "god-men" that you mentioned (some of which weren't even god men at all. Odin was a god, Ishtar a goddess. Baal also was a god. Maybe you could get away with Krishna). But seriously, you're really talking about gods/goddesses, when Jesus, in the earliest traditions, was neither. It wasn't until quite some time later that he was seen to be like God, or part of God, yet he was still seen as fully human.
