I remember reading an article posted on
Free Republic where a legislator in TN was proposing Constitutional Carry.
And, you are right, the resistance from gun owners will be a real jaw-dropper. Here in Arizona it came from many supposedly friendly fronts (we have found the enemy and it is us).
The "training cartel" that suckled at the government teat created by the mandated training and state "annointment" of instructors was (and still is) furious over their loss of what they perceived as an entitlement.
Then the "I got mine, you should get yours" attitude from CCW holders was an eye opener. Then, there was the group that insisted that there was a difference between open carry (no training required) and discreet carry that required training. And, it was amazing how many bought into the mindset that it's best for their government masters to determine who should and should not be able to carry a gun in a state where open carry has been Constitutional for almost 100 years.
If you want to see it done in TN, I recommend a transition from the "they oughta, wanna, shoulda do this," to "I" will do something about this and get other people who want to move from bitching and moaning to actually getting things done. That means drafting legislation, "selling" it to friendly legislators, tesitying in committee hearings and rabble rousing to make a lot of noise. Expect to find your dick in the dirt, but remember, when you fall on your face you are still moving forward. Get up, dust off and get back in the fight. It took AzCDL 5 years to get Constitutional Carry. We "incrementalized" our progress with small victories (ask for the stars and accept the planets) every year until finally everything aligned and we were able to go for the brass ring. It CAN be done!
