I see that NRA decal on the rear window of your car and my eyes narrow. I look at the back of your head in the driver’s seat and I wonder if you are a threat.First of all, I don't have an NRA decal on my truck. I have a Cimarron Firearms decal that reads: "I'm Your Huckleberry."
A threat to my children. A threat to me. A threat to society.
Secondly, who cares what you think is a threat? You've disarmed. You can think all you want about how scary it all is, but your opinion is empty and meaningless if you can't do anything about it. If you want to be able to do something about it, well, you're going to need a gun. And that suggests, per the post below, that it would be wise to get some training and learn to use it safely and well.
The most prominent group you'd want to consult about that is the NRA. When you do, they may give you a decal. You can do whatever you want with it. I have a suggestion, but it isn't printable.
