True. But some are better at putting this attitude in check than others.
Plus, when you have the ability to change your form into a non-dragon form, you learn to walk in some humanoid's shoes and see things from their point of view.
I've never really seen anything that suggests gold dragons are rude to anyone else. Indeed, their 5e stats suggest they should be incredibly smooth, seeing as they have 24 Charisma and both Persuasion and Insight as skills (whopping +13 to the former!) and, if spoken to within their lair, can invoke prescience every round to have automatic advantage on essentially all checks.
To be clear, vote as you like. I'm just not really seeing the "gold dragons are especially manipulative and rude" thing. All dragons do that. Gold ones just favor giving advice, knowledge/training, and/or tools so that mortal-kind can save themselves.
By those lights, silver dragons can be seen as sort of parasitic and untrusting. They don't believe mortals can save themselves, so they have to go out and babysit us. Oh, sure, they
enjoy spending time with the kiddos, you kind of have to if you're going to be in that line of work. But fighting their battles for them, deceiving them into thinking you are someone you aren't, hiding the good you
could be doing so you can have more fun masquerading? Kind of shows a flippant and not very respectful attitude.
Or, if you want a TL;DR: two can play at the "reframe a positive thing in a negative light" game.
