Some well known public non-profit organizations

From Breitbart comes this heart-warming bit of news:

NRA Surges to Record 5 Million Members
At the National Rifle Association's convention in Houston, TX, NRA Executive Vice President Wayne LaPierre announced that the NRA has now grown to an unprecedented 5 million active members. He concluded his speech with the theme of all the NRA officers, vowing, �From liberty�s defense, we will never back down. We will never surrender. We will always stand. We will always fight.�

Well over 70,000 members of the NRA are assembled in Houston, Texas for its 142nd Annual Meeting�projected to break the all-time record for the nation�s oldest and largest Constitutional rights organization. The convention houses over 300,000 square feet of exhibits (mostly firearms and accessories), seminars on various topics including women�s and children�s safety, and formal speeches from national political leaders and the NRA�s leadership. The central focus on the annual convention�as always�is protecting the Constitution�s Second Amendment right to keep and bear arms.

An interesting tid-bit:

...over 58,000 Americans joined the NRA in one day after Obama gave his initial gun-control speech...

May I have another please?

...the NRA�s membership has grown by roughly one million�an astounding 25% increase�since the middle of last year...

Reading the 450+ comments got me to doing some simple fact-checking:

NRA - Organized: 1871 - Membership: 5,000,000
ACLU - Organized: 1920 - Membership: 500,000
NAACP - Organized: 1909 - Membership: 300,000

Hell -- the environmentalists can't even muster a better showing:
Sierra Club - Organized: 1892 - Membership: 1,400,000

I went looking for some of the other 'hot-button' organizations but they don't have memberships Per se: Greenpeace, SPLC, etc. When you have five million members, you kinda own that playing field...
