Everytown for Gun Safety has taken-up the cri de coeur of Dawn Lafferty Hochsprung, the former Principal of Sandy Hook School. “The Be Nice t-shirt honors the small acts of kindness and courage define our movement to reduce gun violence,” Everytown’s email blast declares. While I’m for the first part of the advice – “be nice to each other” – the last bit – “it’s all that matters” – leaves me cold. When you’re facing a lethal threat, such as the spree killer that stole the lives of innocents at Sandy Hook, being nice is not the best strategy. Courage in that situation requires the exact opposite: unrestrained aggression. What’s a better fence-straddler-friendly T-shirt slogan for the pro-gun side?
