I know it's not meant badly, and I know people aren't doing it with bad intentions, and I know!!! that a lot of people who are JGY fans do this
but also I really hate the thing where people like—refer to the character in general as Meng Yao (as opposed to when the time period/his status is specifically relevant). It's like...well, there's this bit from ch 48 for starters:
He continued to walk forward. The cultivator hurried to ask other people. Not long later, he caught back up, “Sect Leader! I’ve asked. The cultivator who kept guard at the end during the last battlefield clean-up is called Meng Yao.”
Hearing the name, Nie MingJue raised his brows, as though finding it somewhat surprising.
Wei WuXian knew why. Before Jin GuangYao was accepted into his clan, he was named Meng Yao, after his mother’s last name. This wasn’t a secret at all. In fact, the name used to be quite “well-known”.
Although not many people saw with their own eyes how it was when Jin GuangYao, the one who would later become LianFang-Zun and stand upon Koi Tower with unequivocal power, first came upon the tower, the rumors had already explained things at large. Jin GuangYao’s mother was renowned in one of Yunmeng’s brothels. Back then, she boasted the reputation of being one of the most talented prostitutes. It was said that she could play the guqin well and wrote excellent calligraphy. She was so well-educated that she could almost pass as the young mistress of a wealthy clan. Of course, no matter how great the resemblance was, in the mouths of the people, a prostitute was still a prostitute.
And then it goes on into how everyone knows the story of how he was kicked down the stairs of Carp Tower. It's a famous name, the name of a famous joke :(
And—you know, it's not a coincidence!!! That NMJ calls him Meng Yao when he does!!!! In the context of the violence he does!!!!
Jin GuangYao still wanted to speak, but Nie MingJue had already lost all patience, “Meng Yao, don’t speak such pretentious words in front of me. Your whole thing stopped working on me since a long time ago!”
Within a second, a few degrees of unease flashed over Jin GuangYao’s face, as though someone with an unmentionable illness was suddenly exposed in the public. There was nowhere for him to hide.
This is at the stairs!!! It's right after this he starts talking back!!!! It's like... it's very much part and parcel of NMJ's inability to respect him!!!
And I'm not saying the 'Guang' isn't an awful insult, of course it is, but I don't think there's any indication he'd rather be called Meng Yao!! Rather the opposite!! He is Jin Guangyao, it's what he fought and worked for, it's the name that means he can be Lianfang-zun, Jin-zongzhu, Jin-xiandu. And like—okay, if you want to avoid the Jin Guangyao you could use A-Yao, or even LFZ, there are options.... And it's like—I mean, in terms of the mother/father thing, he does keep his personal name!!! The 'yao' is the same.
And it's just...it what he wants to be called, you know? I don't think we literally ever see any indication that he wants to be called Meng Yao, indeed rather the opposite...he doesn't want to be powerless and he doesn't want the trappings of powerlessness, he wants power in his own right and that's what the name Jin Guangyao gives him....
I know I am being like. extremely sensitive and stuff I just. :( What it feels like is like...people calling him something he doesn't want to be called, because they think he should want to be that version of himself :((( which presumably is not actually what they are thinking but bleh :((((((
