Reading about microaggressions, and as I understand it, in America (american culture???) the Batkids have at least one or two features each that would have them be discriminated against. Imagine the gut-punch, like, young Dick as Robin saving this guy, being thanked so profusely, and then the next day he meets them and to his horror, they make a snide remark about him and his skin color and his accent and his relation to Bruce. Just.... the heartbreak, for each of the kids, because this'll happen again and again. I mean, Bruce too. Due to his religion. Risking your life every night for a city that does it's best to prove how not worth it it is every day.
