I'm abit confused, can you please explain to me whether it's for/against Christianity? Because I heard that Plato was a Christian, but the allegory seems to contradict that.. or have I misinterpreted it?
You need to find a different source for knowledge. The one you're using is an idiot.
Plato lived about 428/427 BC[a] – 348/347 BC so he died about 3 and a half centuries before Christ was born. There was no Christianity at that time so Plato certainly was not a Christian.
The Cave allegory is talking about man's perception of reality.
It does not have a Christian context, and I agree with the folks who said that Jesus came in way later after Plato died. The allegory of the cave is just a simple analogy on a man's journey on breaking free from ignorance and then sharing all the things he learned to his fellow citizens.
As people before have said, Plato couldn't have been a Christian as he lived long before Jesus. I have heard that some of his words could be interpreted as 'for' Christianity but really it's immaterial as Christianity didn't exist back then. This is more an argument in favour of learning and education being available for everyone as I understand it.
