Then I considered the second amendment and how maybe it's not a terrible idea to have an armed populace should the gov't get corrupt and motivated to oppress. ... Then I thought an armed populace wouldn't matter against a sufficiently armed gov't.
Guns are bit old school. People should be allowed to have their own tanks and fighter jets by now :)
It always amuses me to watch the optimism of gun fanatics who believe they're preparing themselves to resist with their shotguns against a state that has drones and nukes at its disposal.
What is something you used to believe, preferably something concrete with direct or implied predictions, that you now know was dead wrong. Was your belief rational given what you knew and could know back then, or was it irrational, and why?
Edit: I feel like some of these are getting a bit glib and political. Please try to explain what false assumptions or biases were underlying your beliefs - be introspective - this is LW after all.
