Take twenty minutes, and listen to this man speak.
Then, if you haven't joined NRA, spend the $35 or so, and do it. It will take you about five minutes online.
After that, if you live in an enlightened state, take the mandated safety classes (it will take about 8 hours one day), and obtain a carry permit. You're not required to carry, obviously, but each permit completed sends a clear message to your state government and Members of Congress. They may be stupid, but they all can count.
Have a great weekend.
