A bigot is a person who has a hateful attitude towards a group of people that he attributes negative traits to, typically based on bias or ignorance.
Which is exactly what you're doing towards the NRA and NRA members, of whom I and many other reasonable people are among.
What is "kill shot mentality"? I am not familiar with this term. You are aware that ALL cops in all departments are taught to shoot for center of mass and keep shooting until the subject is down, in the event shooting is required? And that this is frequently fatal? And that cops are specifically taught NOT to "shoot to wound" as this is an unrealistic effort likely to fail or result in a miss that might harm a bystander?
