Considering it's a right and you want to use a secret government list with no oversight or accountability or due process.... yes it is.
I disagree on the premise that owning a gun is a right. I didn't comment on this list directly or in which method the government should use to take your gun. I merely stated that owning a gun is not a right.
Sports. As in recognized by the International Olympic Committee and plenty of other bodies. I can tell, I regularly partake in amateur and officially sanctioned competitions.
Also, hunting. Which is a way of life and puts food on the table in plenty of rural communities.
These examples do nothing to prove that guns have a function outside of causing destruction.
