Brother, I am not grumbling, but suggesting a better use of our resources! Thanks for the tip.
You're not grumbling. It reads like grumbling. Let me check. Yep, you're grumbling. You should have spend the time to call the no solitation number from the magazine if you wanted the mailings to stop. If you thought about it, the mailing work or else they wouldn't do them. While you and some others are grumbling about getting off the couch to throw a letter away, there are those who get out their checkbooks to send money.
Try an experiment. The next time you get a letter, send a little amount of money. Each and every time you get a letter. Do it for a year. Then you might feel like the rest of us who get irritated by the 76 million gun owners who won't join the NRA because of a million stupid excuses. You can also get really irritated by the moron Freeper who posts thirty year old "failures" of the NRA because they weren't a lobbying group at the time.
