I wrote about this just the other day from my perspective as somebody who did a lot of social protest in the streets in the 1990s as a member of Queer Nation and Act Up. Agree or not with our tactics, we had something important to say and we said it was active fear of military-style assault weapons intimidating us.
This is something new under the sun. The rights to speak and redress for grievances become far less meaningful went death at the hands of an angry civilian becomes a serious possibility.
Firearms, especially military-style assault weapons, must have no place in the public square.
