Driving a car is not in the Bill of Rights, so I wouldn't hold that up as a comparison, but nonetheless, I agree. As long as you have completed a training course and the state law is "shall issue" and not "may issue" I see no reason for people to work up such a fuss over requiring reasonable training for something that ultimately is designed to kill someone.
The point is that a requirement for a permit, and a requirement for specific training to obtain that permit, creates an irresistible opportunity for a corrupt state to make that training and permit difficult and/or expensive to obtain. The same principle, exactly, that was behind the poll taxes used to selectively disenfranchise certain elements of the citizenry a few generations ago.
I do agree that there is great value in having everyone who is going to exercise their Second Amendment rights, in being trained in how to safely and properly do so. But that training needs to be easily and freely available to any who wish to seek it, and there needs to be no opportunity to use anyone's inability to easily obtain it as an excuse to deny them their rights.
I say that such training should be made a standard part of every high school curriculum; and with that, there should be an underlying assumption that any adult has no excuse not to understand the principles instilled in such training.
