Gary Pudup knows there will be loud and angry voices opposing any attempt to overhaul the country’s immigration laws. There will be plenty of talk about sending “illegals” home, about how they take jobs from Americans and live as criminals in the United States. The furor already has erupted on the talk shows and with political rhetoric, demonizing the estimated 12 million people in the country without proper documents, Pudup said Saturday at a rally for immigration reform in Albion. “It’s going to be a tough fight,” Pudup, director of the Genesee Valley chapter of the American Civil Liberties Union, said about the battle to address the country’s immigration policies. “Let’s not quit. We have a long way to go. This is just the beginning of the fight.”
