I was going to share this exact thought. I engage people on this all the time on Facebook. I keep it polite and positive: "I can understand why you would think that, but have you considered..." I've never had one of those people who are the most vocal change their minds, but I have had multiple friends and former students who said that While reading my discussion with others it changed their views on the issue when they realized the oppositions arguments fall apart very quickly when you push them on it. I encourage everyone to be determined in this fight. It is easier than any other time for people to spread misinformation on the second amendment but it's also easier than ever to defend it and the polling says we are winning the fight. Don't give up, don't quit, it's about changing the minds of the undecided and the open minded who watch the discussion.
