I often see Turgon framed as having, like, this particularly heated hatred of the Sons of Feanor (and Maedhros specifically is the target more often than not) but I don’t think I’ve ever really seen it in text?

Like, the entire host of Fingolfin is noted to have “little love for Feanor and his sons” after the Helcaraxe, and considering Elenwe’s death I can see where this has been extrapolated from, but he tends to be assigned a lot of vitriol that he never expresses canonically to my knowledge. He doesn’t get in fights or make statements of resentment and undying hatred, he’s mostly just doing his own things with Finrod and Gondolin

I really don’t think he is specifically spiteful and uniquely angry at them, at least not to the degree I often see ascribed to him
