automobiles are dangerous weapons that kill many more people than guns. it defies logic to ban the less dangerous item while permitting the more dangerous item.

Automobiles are not meant to harm or kill people; they are not weapons. Classifying them as “weapons” is what defies logic.
I am not sure I would want a scatter brain doctor opperating on me. Howe ver I am not sure that scatter brain would be as worrisome a trait for someone carrying a weapon. Fr instance someone ith ADD my forget to load it or may not remove the safety while attempting to fire. It is unlikely they will randomly have lapses of judgement and pull it out fire it irrationally. If they are of the mind set that would be irrational with a weapon, there is a high probability they will be irrational in other areas as well. Being irrational would make it difficult to succeed in areas that would require a college education.
My experience with peole has been far different; I do not share your thoughts here. There are many, many irrational professionals out there.
I did not mention that I presumed this would be for college kids who were at least old enough adn properly trained to carry a weapon in other circumstances. Obviously this would not apply to 16 and 17 year old college students.
So are all 18, 19 and 20 year olds “old enough”? Again, in my experience, “old enough” is a very wide open term…and that’s the problem, isn’t it? There are 14 year-olds that are “old enough” to fly airplanes (very few).
I see the entire problem that we’re discussing as there is no single criterion to judge a person on whether he or she is competant to carry a firearm to be used for the protection of others (in a Columbine or VT situation. Agree?
As for your cardiologist I would hope that he is responsible enough to know his limmitations.*** For instance does he only take public transportation and not drive a car? Let’s face it it is much easier to have a short lapse of attention and kill with a car than if one were carrying a loaded weapon.*** I do know some “savants” that know their limitations and as a result choose not to engage in activites where they do not feel they can execute them safely including carrying or using weapons.
Perhaps. But there is the intent there as well. I believe your comparison to be flawed as an automobile is never meant to be used to hurt or kill someone or something; this is the sole purpose of a firearm (except perhaps for pointing it at someone to scare them off).
