Which group promotes itself as the watchdog for Second Amendment rights in the US?

The group that promotes itself as the watchdog for Second Amendment rights in the U.S. is the National Rifle Association (NRA). The NRA is dedicated to advocating for the protection of the right to keep and bear arms as outlined in the Second Amendment of the U.S. Constitution. It engages in various activities, including lobbying for gun rights legislation, educating the public about firearm safety and usage, and mobilizing grassroots efforts to influence public policy.

The other organizations mentioned focus on different areas. The NAACP (National Association for the Advancement of Colored People) primarily addresses civil rights and issues affecting African American communities. The NSC (National Security Council) is involved in advising the President on national security and foreign policy matters, rather than gun rights. The NEA (National Education Association) mainly focuses on educational issues and supporting educators, rather than Second Amendment advocacy. Therefore, the NRA is clearly positioned as the defender of Second Amendment rights.
