As a former Anti...
Allow me to chime in here.
I'm certain most of the politicians pushing gun control are doing it for political gain. Some of the more vocal antis, I'm sure, get a thrill out of the power their advocacy gives them.
Joe six pack? Well, I can tell you, there's an overwhelming amount of anti-gun propaganda out there, being peddled by the schools, media and government. When you grow up in a government indoctrination center, being taught that guns, pictures of guns and chicken pieces shaped like guns are bad, you tend to agree. Particularly when you aren't taught critical thinking skills in that same indoctrination center. It takes a lot to overcome those teachings received as a child.
I will echo Vermont and RPCVYemen by saying that calling them names isn't the answer. We have to fight this a little bit at a time, and not just on one front. Education is the key. Be friendly and informative. It may be necessary to teach logic before approaching the issue of guns. Influence the school boards, or keep your kids out of public schools, even better. If people are taught that guns are bad at an early age, that is what they will believe.
