Considering how I'd never heard about any sizeable backlash for any other voice performers in FF14, I had assumed that it wasn't a coincidence that the only such backlash was towards a trans performer. But I play with Japanese voices so I never heard her English voice.

Until I did. My spouse finally played through the Wuk Lamat stuff and I had the opportunity to hear Wuk Lamat's English voice, and I was honestly startled...because Wuk Lamat's voice acting is easily in the top 20% of the English game's voice acting. Is it great compared to the acting in Baldur's Gate 3? Nope. But compared to the majority of the English voice-acting in FF14, it's hands-down a homerun.

The idea that any person who can tolerate the Scions' flat droning delivery would find Wuk Lamat's acting so bad as to be worth campaigning against is so backwards that there's really no way to make sense of it without asking the question, "Okay, but what is this really about?" And once that question is asked, the answer is transparent.
