How much time have you spent in Australia?  I was only there for one month, but of the 25+ countries I've been to, I felt the most familiarity with their culture (I have lived most of my life in the U.S. and the majority of that in Alaska). 
I agree we may be too cowardly, and our representatives too bought by the NRA, to get anything done.  But I'm not going to give up and let the crazy gun nuts aided by the NRA rule.  Are you?
