I belonged to the NRA for a while.
They probably mailed me further solicitations for $$ on at least a monthly basis.
I pointed out the them that they had probably spent any money they'd gotten from me on mailings asking for more---that i had their address should i wish to further contribute and to please use what i'd sent more constructively.
Righteous self defense, lives saved, property protected, by lawful use of firearms probably happens many times a day.
If i saw an incident published in daily paper occasionally, "paid by the nra"---I'd be back on their mailing list--
