The "Piers Morgan Live" host praised the U.S. as "a land of true opportunity," adding, "The vast majority of Americans I've met are decent, hardworking, thoroughly dependable people."
But he went on to say that an estimated 100,000 Americans per year are hit by gunfire, and argued, "I am so pro-American, I want more of you to stay alive."
Morgan expressed frustration with reaction to the Aurora, Colo., theater shooting and the Newtown, Conn., school shooting: "I assumed that after 70 people were shot in a movie theater and then just a few months later 20 first-graders were murdered with an assault rifle in an elementary school, that the absurd gun laws in this country would change, but nothing has happened." He added: "The gun lobby in America, led by the NRA, has bullied this nation's politicians into cowardly silence. Even when 20 young children are blown away in their classrooms."
Earlier this month, National Rifle Association CEO Wayne LaPierre declared, "There is no greater freedom than to survive and protect our families with all the rifles, shotguns and handguns we want."
A study published in the American Journal of Public Health last year found that states with more gun ownership often had higher rates of gun-related murders.
Morgan argued Friday night: "More guns doesn't mean less crime, as the NRA repeatedly tries to tell you. It means more gun violence, more death and more profits for the gun manufacturers."
He concluded, "Now it's down to you. It is your country. These are your gun laws. And the senseless slaughter will only end when enough Americans stand together and cry, 'Enough!' I look forward to that day. I also look forward to seeing you all again soon. Thank you. And God bless America. Oh, and while I'm at it, God bless Great Britain too. Good night."
