American gun laws summed up in memes

[Eclipse]

For an outsider who knows very little about the US constitution, I read the second amendment as basically saying, and I am probably very wrong here, that citizens are permitted to bear arms for the purpose of maintaining a well regulated militia in defense of the security of a free state.

Now, when I hear interviews on gun ownership in the US, the majority of citizens explain that they own guns for the purpose of self protection and hunting, not for defense of the state. I am wondering actually how many US citizens are members of a well regulated militia? From what I read and hear, I would hazard a guess and say the majority of US gun owners are not members of a militia group.

If this is right, could not the government indirectly regulate gun ownership by insisting every gun owner in the US comply with the second amendment and become a registered member of  a well regulated militia group and then, in turn, ensure the militia force is very well regulated ?

It seems pretty straight forward to me and i'm sure if some blow in from across the Pacific can think of this then it has already been considered and debated in the US.

 I'm wondering what the arguments for & against this strategy are or were.

Edit:  Sorry for no meme. Just had this thought in my head, didn't want to drag up an old thread and really didn't want to start a new one.
