Some quotes from the snip in the OP:
I however do not understand the need to own an assault rifle for private use
I have to wonder why someone would purchase ammunition or a weapon for that purpose.
I however see no benefit, unless you’re camping
The person can have those opinions all he wants. He is not God and his “personal sensibilities”, such that they are do not trump the constitution.
A common misconception about the Constitution, is that it grants rights. That could not be further from the truth. It merely recognizes some of your God given rights. The main purpose of the Constitution is to limit the federal government. The Constitution draws heavily upon natural law, and even if the Constitution were amended to eradicate the RTKABAs, that would be in violation of your God given rights. Basically, our natural rights cannot be infringed upon by any organization of men. They simply do not have the authority.
