Those opposing Initiative 1639 based on the Constitution are selective in their demands. Somehow it is against the Second Amendment to deny long guns to people under the legal drinking age, but it is perfectly acceptable to deny such people access to hand guns. For that matter, they want all legal adults to have access to semiautomatic rifles but they do not demand allowing everyone access to fully automatic rifles or bazookas.
When will the NRA act consistently and begin campaigns to allow free sale of hand guns to people younger than 21?
If they are willing to admit that it is legal to prohibit some categories of arms, perhaps they should instead address the issue of what are the acceptable reasons to prohibit hand guns but not prohibit what seems the weapon of choice in mass murders.
