In Australia, we use the expression Tall poppy syndrome for a "social phenomenon that occurs when someone's success causes them to be envied, resented, criticized or discredited."
Conversely, is there a term or expression that's used for a social phenomenon where successful and popular figures are respected and blindly defended only because they are, well, popular and successful. I notice this behaviour in the YouTube world where smaller channels (or lesser known Youtubers) get extreme flak for criticizing popular channels, no matter how right they can be.
- Critic: I cannot stand this person. His opinions have no basis. I can't believe he's so popular.
- Fan: Oh my god, you're such a pathetic jealous hater. Get a life!
- Critic: Wow, you sure suffer from [insert expression or word]. People like you are hilarious.
I am fine with an idiom, a single word or an expression. Just whatever fits.
