"Why do you need an AR15?"

[stanc]

To Answer your question - I don't need any firearm. I choose to have one as it is my right, same as it's my right to post here...

You have no right to post here. It is a privilege granted by the owner, controlled and revocable by the moderators.
However, the comparison to gun ownership is pretty accurate. Your "right" to have one is restricted and revocable.

Vehicles and driving is a privilege, and the most regulated of anything that I can think of if you really chew it down to the bone. Still kills more people than guns, cancer, medical malpractice...and it a freaking privilege not a right.

It always amuses me when gun people interject that into discussions.
It is the government that defines what are legal rights and privileges.

P.S. Cancer kills over 20 times more people than motor vehicles kill.
