When right wing activists and media personalities (falsely) accuse Tim Walz of deliberately misrepresenting his military record, they’re not just attacking his honor and integrity, and therefore his character. The actual—although unspoken—target of the attacks on Walz’s career in the Army National Guard is his masculinity.
The reason is straightforward: Military service confers a certain kind of masculine street cred on men who wear the uniform. As a result, when a male candidate has a record of service—especially if he’s a Democrat—right-wing operatives make it a point to plant seeds of doubt about whether they were truly worthy of that respect. It’s a battle tactic in the political war. The ultimate goal is to punch holes in the “real man” credentials of someone like Walz, and thereby undermine his popularity with men.
