That just doesn’t track though. Even if you take as a default the average Stormwind rando doesn’t know anything about dragons A) most people in these riot scenes tend to be actually rather experienced sorts, and B) using that to apply to dracthyr is really…weird?
Again even if you feel the baseline Stormwind random person opinion is ‘dragon bad!!!’ (completely ignoring the massive cultural connotations green, red, and bronze flights have had through history) that’s still QUITE a leap to go right to ‘we gotta riot over these dracthyr!’
Dracthyr come in all colors and styles, so even if the average human has only loose history of what dragons are, that ignorance would lead them to assume that, say, a green colored dracthyr would be a green dragon, aka the hippy dippy dragons the night elves seem to bro out with more than anything, a bronze would be a bronze dragon aka the weirdos in the desert who kinda don’t do anything 99% of the world interacts with (hell I’d argue if we’re treating the average Stormwinder as THIS ignorant they shouldn’t even know bronze dragons exist?), a blue one would mainly remind them of the guy who runs Dalaran, the city that is a major ally of Stormwind’s, and the reds would just be ‘that’s a weird colored lizard’?
The only flavor dracthyr that would invoke knee jerk ‘THIS IS LIKE DEATHWING, BAD!!!’ reactions would be black scaled ones and even then Wrathion, the close friend of the former king who literally helped save creation from the old gods personally escorted them into Stormwind to vouch for them. I’m not saying that means every dracthyr is above reproach but again if we’re using this massive level of ignorance about a fairly major race of the world as baseline most people wouldn’t know about the whole ‘Wrathion also kinda started the whole WoD storyline and domino-effected our other previous king getting ashed’ part of his story.
I’m not even saying it’s ‘wrong’ to be xenophobic about them ICly, even from more seasoned types, but it just feels really weird to say 'actually the baseline level of awareness of the world for a random Stormwind commoner would be so lacking that they wouldn’t know anything at all about one of Azeroth’s major races through its history that they not only assume every dragon is Deathwing but would look at a green scaled elf with shiny gold hair and go 'this mf’er’s here to do Deathwing stuff, GET ‘EM!’
You’re saying the baseline level of knowledge is both so deep that random Stormwind people know the Infinite Dragonflight exists and is a danger to the reclusive bronze dragonflight, but also are so pig ignorant they think everything even slightly draconic is Deathwing 2 Electric Boogaloo.
Like, the hoops you have to jump through to say ‘actually roleplaying yet another race riot as a reaction to a new race being added to my fantasy video game, as I do every new race including fluffy pandas and ‘literally just high elves, a race we historically were close friends with’ is actually quite logical and normal’ are so high it feels so much more weird than just going ‘eh I like being edgy’.
