I've never advocated taking away guns. I have no idea how you came to that conclusion. My relatives are avid hunters, and would probably string me up, if I said that.
Not calling you a gun grabber but you don't want people to have a 50 cal weapon right? If you are ok with it I sincerely apologize.
I'm saying that it doesn't pass the laugh test, to suggest the primary reason to have guns is to rebel against an authoritarian government, thus replacing it with a fair and democratic one. First, that's not what the founders primarily envisioned with the second amendment, second, looking to the modern history of violent armed civil war in authoritarian countries does not give on comfort that the end result will be a fair and democratic society.
It doesn't have to be the primary reason it only needs to be a supporting one. I make this one for arguing gun rights because I know liberals will be most sensitive to it because of the current admin.
In contrast, the power of labor unions and civil disobedience in authoritarian countries, has a MUCH better track record.
Labor Unions are very weak in this country, and civil disobedience only works against regimes that are sensitive to the feelings of its constituents.
