How can anyone one 'love' guns when they kills so money people?
Well, I'm guessing it's because they enjoy the skill of shooting at targets. I it is considered a sport. I have no objection to that at all. I have in the distant past taken part in shooting competitions at country fairs and the like. Very enjoyable.
The argument is weak, how can one love cars when they kill so many people?
The key to the issue lies in effective legislation and control, not criticising people for enjoying something, be that guns or cars.
