[Roscoe]

The intended use of a guns is a threat to those around the user, therefore a violation of their rights.

All human activities have societal consequences. The implication that all activities are "essential liberties" is juvenile nonsense.

The "right" to use crack doesn't equal the right to keep and bear arms.

"They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." --Benjamin Franklin

Franklin wasn't a simpleton.

[Alan Chapman]

All human activities have societal consequences.

Assuming (for the sake of argument) that's true by what measure does one go about determining which activities should be prohibited? Which activities are rights and which are not?

The implication that all activities are "essential liberties" is juvenile nonsense.

Your misinterpretation of Franklin's quote is juvenile nonsense. He's talking about liberty being essential and not which liberties society considers essential.
