Hillary Clinton gave a speech Monday addressed to, well, me. In Philadelphia, the Democratic candidate for president delivered an address aimed explicitly at “millennials”—those of us born, roughly, between 1982 and 1998. (Like all bogus pseudoscientific categories, who exactly constitutes a “millennial” is only roughly defined.) As Clinton evidently sees it, we millennials care only about a few things—student debt, paid leave, and raising the minimum wage among them. Message: she cares.

There are myriad flaws in this approach. But just to point out one: People have many identities distinct from the year they happen to have been born. I’m a millennial, sure. But as a city dweller, I could be concerned about rising crime. As a denizen of the nation’s capital, I might be concerned about terrorism. Of what relevance to those issues is the year of my birth?
