This may help you understand. In the gun world there are various competitions that focus on speed, efficiency and accuracy. Consider it like a competition of speed golf. Thats one practical reason although your missing the point. The question answers itself, it a RIGHT not a privilege or reason. But I get where you’re coming from . Change your wording from right into reason and I just gave one of many. At the end though as a RIGHT I should have no need to justify why I want or use one anymore than you would need a reason to justify burning the flag . I would disagree and say you cant have a possible reason to do so but it is your RIGHT under the first amendment to express it in your own way. Hope this helps without FLAMING you.
