Protest proposed anti-gun "laws"?
Get out and vote?
Write your congresscritter?
Sorry, I can't get too worked up for all that. I don't buy into the idea that gun owners who don't speak out are "doing nothing".
Sometimes people just realize that political action is equivalent to trying to use a trash can lid to hold back a landslide. I'll spend my energy doing things that might work.
It's always going to be something- you'll spend your life in a dither trying to put out each brushfire of tyranny if you keep seeking a political "solution". The State- government- is illegitimate. That is NO WAY to deal with other people. Accept it and move on to more productive pursuits.
Unless you just happen to enjoy the frenzy of reactive political action- and some people do. In that case, do whatever makes you happy, but don't pretend your path is the Only Way.
