That would be enough for me to cancel my membership, as they would no longer represent me.
Once you join the NRA, you cannot drop out.
Once, in the early 80s, I decided to let my membership lapse.
I was deluged non-stop by NRA junk mail and NRA marketing phone calls. Day after day after day. I asked them over and over, by phone and mail, to stop contacting me. After several months, I renewed and the harrassment stopped.
No one believes in the NRA mission than I do, but they were the most obnoxious people on earth when it comes to marketing. I don't know if they are still like that or not; I haven't dared to let my membership expire since then.
