Again....But it's never the guns!

[Tiberius]

That tyrant can only be your own government and if that is the case, well one can only conclude that there is some terribly wrong over there.

...and that tyrant was their own government. They used to be British citizens, and the tyrannical government was the British Empire, not allowing them representation whilst still taxing them.

The founding fathers realized that things could get out of hand again, so they made it so that ordinary citizens could take up arms against the government if they needed to. That is the entire point of the amendment, and why it still stands today.

If your government starts oppressing you, you have the right to fight back against your oppressor. The second amendment means that your government can't try and bully you into submission by hoarding all the guns.
