an insult to one is an insult to all

an insult to one is an insult to all

The belief that, when one person in a group is insulted, the insult extends to everyone in that group. A: "Was I rude to her? Yeah, probably—but I didn't mean it as a slight against everyone who's in a wheelchair!" B: "Maybe not, but you're a prominent politician. From the media's perspective, an insult to one is an insult to all." Just remember that most of the people in this neighborhood are Polish, and an insult to one is an insult to all.
