Yes, Rarity did bring it on herself. I would agree with that.
It is highly characteristic of her to assume that someone in the nobility must be noble in temperament.
It’s only shown in the Fluttershy micro that she has discarded that notion.
And I’m on the fence about whether her expectations were reasonable. On the one hand I didn’t think she asked for much, but on the other it is some random guy.
And it is worth noting that most people tend to dislike Blueblood for the wrong reasons.
He isn’t a jerk because he didn’t hold doors open for her. He’s a jerk because he didn’t even care or try to pretend for appearance’s sake.
He obviously regarded her as beneath him, which is rather rude.
People view the relationship through gender googles when it’s really classism.
