The less funny thing now, is that the West has reached that level of absurdity without noticing, because a women sleeping with her hijab on, or an underground black creature (ork), or a black medieval British princess (as seen on some BBC shows), is pretty much the same level of insanity.
And you're right, of course there is nothing political in that. :)
I don't think the story is coherent enough to be making a real political statement, even if a few scenes gesture wildly at a few vague (and contradictory) political ideas.
His point was literally that "having black people in stuff is political", so what exactly is your argument? Tolkien described elves as fair skinned, so there must have been an explicit decision by the show runners to override this, for reasons that could reasonably described as political. If you think that equality / equity etc agenda is not political "because it is the right thing to do", maybe take a moment and reflect on that.
Edit: See e.g., The Silmarillion, ch. 11: "for the Sun was set as a sign for the awakening of Men and the waning of the Elves, but the Moon cherishes their memory"
Which is all to say - I don't see any relationship with skin color.
When looking in the Silmarillion, it seems that they primarilly loved the stars and aspecific preference forthe moon is not mentioned. However, the moon came first (as the elves, compared to the humans) and traveled over the sky several times before the sun first appeared; "Isil was first wrought and made ready, and first rose into the realm of the stars, and was the elder of the new lights, as was Telperion of the Trees. Then for a while the world had moonlight [...] Tilion had traversed the heaven seven times, and thus was in the furthest east, when the vessel of Arien was made ready" and "the Sun was set as a sign for the awakening of Men and the waning of the Elves, but the Moon cherishes their memory"
Why it matters? So, in my opinion, that the elves may be fair or perhaps pale in the skin makes sence symbolically due to their relationship to the night and the stars (and perhaps the moon). Also, in humans, there tends to be a relationship between the sun exposure of an area and skin color but I don't think we know how this affect elves (how their bodies work, some born before the sun was created, living for very long time, etc.)
But also - orcs also hate sunlight, yet have darker skin. And harfoots have darker skin but prefer the sun. (And trolls also prefer the moon, for different reasons.)
So even trying to find some thematic association within Tolkien... it's just not there.
