People who have never seen dragons see a woman from a foreign country, whose father was the "Mad King," marching into their homelands and don't know what to think. So xenophobic.
Right, so maybe understand why they may feel a bit xenophobic. Beyond that, the old gray mare that told Bran stories in Season 1 said that these were all legends that could never come true. But sure, these northern farmers should instantly have a change of mind when they're told that the things they've been hearing are ghost stories are actually true.
No, I am not at all confused. You seem to think redemption and redemption arc are synonymous. Newsflash, they are not. A redemption arc is a writing tool, used quite often. The show writers have even gone as far as to say Jamie was on a redemption arc, and you still deny it, which is hilarious. As to whether or not you personally think jamies current/recent actions have redeemed his actions in the past is irrelevant, matters like this are left to the court of public opinion. I don't claim ownership, I claim to be with the majority.
