Does it end with my possessing bombs and missiles?
with my possessing automatic fire weapons? Assault rifles? rifles that hold more rounds than someone else thinks is OK? with my having a handgun in the car? with my possession of a hunting rifle? with my carrying it around loaded? Just where?
My point: The Second Amendment is not absolute, and can not be. it has to be interpreted in the context of the 21st. century. It is not, therefore, a matter of "supporting" it or not, but of agreeing on just how far it really goes.
Therefore, people who don't want to take it as far as you aren't anti second amendment, just anti your point of view.
