While there is no reason to resort to violence unless responding to a credible threat, there is every reason to be prepared to respond appropriately to violence. These morons are inciting violence and just like Antifa, they are likely to follow through with their threats. There is no rule of law saying that one must get a beating. or get shot, or accept any other form of injury before defending one’s person or loved ones. So remain calm, load magazines, and confirm your zero while listening closely to what your enemy is saying. If they are promising death to you, be prepared to defend with deadly force. Sounds like these folks are threatening innocent citizens to me. IMHO.
