rr said:The right to keep and bear arms was not guaranteed to us because of the potential for them to be a benign object.
It is not guaranteed because it may stay in a gun safe its entire life.
It is not a right because it is fun.
Participation in any sport, whether specifically or generally is [not] promised.
Who argues otherwise?
rr said:To deny the purpose of arms, armaments in essence denies the inherent right to own and use them.
That is a non-sequitur based on an assumption of the issue in question.
One could deny the legitimacy of the purpose to which someone puts a hunting rifle (linguistically similar to a sporting rifle) but it is still an arm and still related to the expressed right. Nothing in discussion of the legitimate purposes to which people put their arms is itself either a denial of affirmation of the right.
rr said:Once it becomes a dangerous sporting activity and implement, it is free for government to infringe upon.
Government can infringe car ownership.
Government can infringe upon smoking and drinking.
Government cannot infringe upon the keeping and bearing of arms (weapons) .
Note that you didn't need to reference an alleged purpose of an object to state the right.
