Doing so further validates the presumption that the federal government has the right to decide who gets to exercise their constitutionally protected rights and how they exercise those rights.
This is why I don't send money to so-called Second Amendment lobbying organizations. I haven't found one that truly believes that the Second Amendment protects the right to keep and bear arms and that the right to keep and bear arms is a natural right of an individual.
It would be counterproductive for them to believe such a thing. They need the never-ending threat to survive.
