My approach was if you educate the naive, (their financial base) they will no longer donate to those evil organizations and then they will fold from lack of support....
With all due respect, I don't disagree with your tactic, only its scope. The MMM is zip! Means nothing. Its the yearly pledged donations from Monster .Com and AOL-Time-Warner that the non-profit and not-for-profit political activists organizations use to buy their BMW's. That's why so few people can make such a big stink, they have big money, not a big movement. That "Big Money" money, however, is also made available to the likes of Chas. Schumer and Diane Feinstein.
As Rush has always said; "Follow the money". Gun control is no different. If Browning, Colt, Ruger, Berreta, Glock, etc., had had the foresight to just hire away the executive directors of the gun control organizations, we would be time and money ahead and we would not have lost so many gun rights and the manufactures gun sales. As "Pogo" said: "We have found the enemy and they are us!".
