Former presidential candidate and activist Ralph Nader has criticized the rising outrage over “microaggressions” as he mounts a campaign against perceived elitism at his alma mater.

Nader, a Harvard Law graduate, is seeking a seat on Harvard’s board of overseers, one of two governing panels that comprise the school’s governance. He’s running as part of what Politico described as a “protest slate” of candidates, who are advocating a more transparent admissions process. However, he’s taking heat for the associations of some in the group with anti-affirmative action stances.
