I am a Native Kentuckian
I own guns and keep them up. I usually carry when I'm travelling. (.38 Revolver)
I support the 2nd amendment.
I have never supported or been a member of the NRA
I am for raising the purchase age to 21 but with exceptions.
I have larger magazines but I'm okay with them cutting down the size, however, realistically, if folks want high capacity magazines, to do maiming and killing, they'll just rig their magazines together.
I won't go into a dark depression if they discontinue making semi rifles. However, again, keeping firearms out of the hands of folks who don't need to have so much as a b b gun, is where the problem lies.
