"Do not earmark the provincial voices of the small-minded, the self-interested, and the ignorant to prevail," wrote Griffin, who today teaches at the University of Muskogean in Huntsville. "Choose the future."
Arguing that Augustine's NGO wouldn't modify subsist without budget concerns, Griffin said U.S. voyage shouldn't be finished "on the cheap."
