Mate there isn't much a point in debating him, he is so firm in his opinion it is factual to him, even if reality differs, you can't get conversation only dogma from him and a few others here.
On the topic of Galadriel, you think they will even hint of the fact she should be married to Celeborn during the show? I give it a 50-50 they make an offhand remark that he is dead or gone. I seriously hope they don't ship her (a bit on a nose currently) with the totally not Sauron Halbrand dude. It would fuck her character even worse, not to mention it would be the 2nd human-elf relationship they are adding to lore (almost doubling Tolkiens count over all the ages).
Also looking back at a few things, they REALLY did Celebrimbor dirty. They made him appear to be much older than every other Elf (roughly same age as Gil-Galad and Galadriel), they gave him that terrible outfit, took away his friendship with the Dwarfs and gave it to Elrond, seemingly took away his love for Galadriel, and altogether haven't done much to develop the man who would craft the rings of power. They could develop him some more, but with the current cast they are focused on not to mention the Numenorean's coming up I seriously doubt he gets much screen time (Gil-Galad as well).
