A portion of the the First Amendment is protected by media litigators. It's got more than a few important protections that deserve defense. Besides, are you really complaining that there are too many organizations working to protect our civil liberties. Seems an odd complaint. If Second Amendment rights matter to you then, by all means, donate to the NRA or others fighting to protect that right. Doesn't mean the ACLU and others don't do important work as well.

I donate to a state-level 2nd Amendment rights organization, GeorgiaCarry.org, rather than the NRA. Why? Because GeorgiaCarry stands strongly against racial discrimination and is working hard to end Jim Crow era Georgia laws that to this day attempt to thwart non-white citizens voting and asserting their 1st, 2nd, and 4th Amendment rights. By contrast, the NRA has a consistent record of remaining silent on race issues when they intersect with 2nd Amendment challenges.
