No, it is not “about the love of shooting someone.”
That is a really bad and dumb generalization.

I Never said, “guns are designed for killing.’ That is a lie.
You do not get anything. You seem to think you have a window in to the minds of millions of gun owners. It is odd.

What possible need is there for automatic weapons? How are automatic weapons relevant? It is extremely difficult and expensive to obtain an automatic weapon.

What possible need is there for an assault rifle? I would have to define ‘assault rifle’ for you, but in this context it is irrelevant. As I said, my friends and I hunt with bolt action rifles. Unless it is birds, of course. For birds we use ground to air, heat seaking missles. 

For trout, we use plastic explosives made to look like Mayflies as firearms are not allowed in streams.
