[I]f I want to talk to someone, for half an hour, even 45 minutes, an hour about gun violence and why nothing has been done to reduce gun violence in this country, I can do it. I’m 65 years old, I’m the boss of me, I run my own show and I can speak out about the need for sensible gun laws, and I can be an activist, and everyone should be an activist before they have a fourth grader killed in his or her class or before they have a grandparent killed buying a quarter of milk, right?
