The NRA has consistently advocated the unfettered use of guns not only for protection, but if they feel to overthrow the government. This fits the definition of a terrorist organization. Extremists are the same whether they are foreign or domestic. They have become a domestic terrorist organization, complete with threats of violence and retribution.
Why is this important?
My wife works in a trauma ER and sees the damage guns do on a nightly basis. We need to get things back to a safer and civilized nation.
