I don't think anyone sane does.
Most decent people just want to live their lives in peace, and will put up with a lot of difficulties thrown in their way without doing much about it because of not wanting to get into a big mess trying to fight it. I know I am that way, and the vast majority of the people in society are that way.
Which is good, as we really need to trust each other to abide by the rules in order to live in a society such as ours.
The change is going to come when a group of people who know what they are doing and are able to do it decide that they have had enough and are willing to sacrifice everything they have and act with purpose.
Kind of like our founding fathers, but with modern technology...
"Abide by the rules" is a two way street, and when it comes to the 2nd amendment, the federal government is corrupt, rotten to the core. That includes all three branches. They lie, distort, and misrepresent in ways that are stunning for being so brazen.
In 1939, Miller's indictment is quashed, and the 1934 NFA is said to NOT apply to weapons that DO have a military use. Come 2008, the Supreme Court (in Heller) says Miller was CONVICTED (he wasn't even TRIED!), and that it would be stunning to read the case as being critical of the 1934 NFA.
The government has no moral authority in this area, and governs from pure threat and use of force against the public.
Trust the government? Heh. No way. The Mafia has a better code of honor than the government does.
