Galadriel aided by Nenya... as powerful as Melian?

[Inderjit Sanghera]

Im sorry, but I cant see where the misunderstanding is.

You quote:

Tolkien even states that only Sauron, physically present in the borders of the Wood with the power of his Ruling Ring, would be able to enter and break the defenses of the Wood. Meaning that not from a distance, and certainly not without his ring, Sauron could not enter Lorien. Much less conquer it

Differs from the one that you based it on. There is no mention of the ring being the only way that Sauron could overcome Lothlorien.
