I have no idea how this hypothesis ("guns protect from oppressive governments") is still holding people's minds captive. The current regime in the US disproves this every day, constantly eroding civil rights and not even being subtle about it. And the people with guns mostly either cheer it on or pretend it's not so bad (until they themselves feature in /r/leopardsatemyface).
