This is great video explains why:
Pass the Torch of Freedom.
"If we spend all of our time focusing on the the anti-gun legislation, but ignore the anti-gun generation; if we spend years as pro-gun activists, but only minutes as pro-gun mentors; if we win the support of this generation of office holders, but not the next generation of voters; then we will have failed."Think about that for a moment. And then ask yourself what you can do to instill a sense of liberty in, and therefore protect liberty for, the next generation?
