At least according to the first post in this thread "The Socialist Rifle Association is a non-profit, membership-based organization dedicated to upholding the right of the working class to keep and bear arms and to promote the development of skills for self and community defense."
The "working class" (however it is defined on a particular day, by whichever Maoist is in charge) is not the same as "the people" as used in the Second Amendment.
We all know what happens when they decide you are not in the "working class."
