There is no sound argument against the application of Prior Restraint to the right to arms.
Actually I gave several that are very sound arguments, you not liking them doesnt make them invalid. Just dismissing them out of hand does not make them sound.
No, you didn't. Each of the arguments you gave were defeated in detail or left with points undefended - indeed, the only attempt you made to show the difference between the rights was, at best, superficial, and you made no attempt to show how that difference negates the application of the concept of Prior Restraint to the right to arms.
The biggest problem you face is creating a sound argument as to why or how such a protection shoudl not be applied to ALL constitutionally-protected fundamenbtal rights, which necessitates that you show how/why some fundamental rights are more worthy of protection than others.
