The one X-men movie is a great example of what I am talking about. The director or writer (one of them) said that it was a metaphore for dealing with homophobia, and sorry but if gay people could shoot death lazars out of their eyes it wouldn't be a phobia, there would be a very strong and legit reason to be afraid of them. Doesn't mean you can't enjoy the movie, just means the trope it is built off of is kind of weak.Oh that's understandable. On your point, I was reminded of the X-men when you talked about fear of powers. Many Shows go into this type of argument, and I've even seen an anime which waded into the matter of psycopathic behavior with an analogy to psycic powers and those in the position, and mental constitution, to kill others without empathy. Anime is probably a wierd one to bring up, and may turn you off, but that show has had me thinking for the last 6 years or so.
But for rings of power, I liked its use of this trope. Makes me wonder how bad things have been in the thousand years from here to LOTR that the dwarves could never sit down and easily share a brew with an elf. But the biggest thing, for me, was the subjugation of some of Man by the Elves. The southerners did fight for Sauron in the previous war, so it does make sense that there is contention and distrust between the two sides. Not the most ground breaking or impactful take on the topic, but I did enjoy that aspect.
Also reminds me of one humorous take on the lord of the rings, which states the orcs are actually more egalitarian and social advanced in ways then the other groups. The other groups that all live separately. It was along the same lines as the review of The Wizard of Oz that points out the Good witch is the bad one. The wicked Witch just wants he dead sisters property back and Glenda sends a child assassin after her.
