Considering that there are no "common sense" gun control bills, I fail to see your issue.I remember a time when the National Rifle Association's (NRA) primary role was to promote shooting sports, teach gun safety, and even sponsor (help build?) shooting ranges . . . all in the name of educating and supporting the next generation of shooting enthusiasts.
They were involved with high school and college shooting teams, supported Boy Scout merit badge acquisition (for shooting), and even helped support the shooting portion of some JROTC programs in cooperation with our military. Their members were the definitive experts on gunsmithing, customization, ammunition, reloading, ballistics, range etiquette, hunting, and all other things related to weapons and the shooting sports.
Over time the NRA has strayed from their original 'mandate' and have become nothing more than a lobby group and PAC (Political Action Committee) whose primary purpose now is simply to raise money and fight any and all gun regulation bills, regardless whether those bills are based on 'common sense' or not.
Though I am a paid Life Member of the NRA, I no longer support most of what they do, and will not support them until such time that they get back to doing what they were originally meant to do - educate and support the next generation of shooting enthusiasts.
