Many people on the right who are in favor of the right to own guns do so based on reasons such as safety. For example, in the wake of pretty much any mass shooting, you will have people come out and say that the solution is to equip even more people with guns so that they can intervene and take out the shooter in such situations. Other examples include simple home security against robbers and what not.
But these same people also tend to oppose gun control policies such as competency tests and strict licensing prior to the acquiral of a gun. How is the co-existence of these two sentiments justified?
One would think that if the usage of guns is purely a matter of safety, then competency in using those guns would be a high priority. After all, if we want to equip people with guns to protect us from robbers or deranged shooters, we would want to ensure that they are as competent in using those guns as possible. And if a person can't pass a competency or licensing requirement, then perhaps they shouldn't own one.
So, what arguments are offered by these people to justify opposing gun competency tests?
Note that I am well aware that many people oppose competency tests because safety is not their primary concern. Rather, they just really like guns, and competency tests is a possible barrier that could prevent them from getting more of them, so they oppose it. My question is not about these people, I am speaking solely of people that concede that safety is their primary concern yet they still oppose competency tests. What arguments do they use to justify such a position?
