It's not a deflection because gun ownership has nothing at all to do with this.
It does. It has to do with your morality, choices, and life.
You are against a 'suicide' culture because everyone might kill themselves of their own volition
But are you in favour of a 'gun culture' in which in which people are killed against their own volition?
I don't think you can be one and not the other.
I have watched someone die slowly in agony, losing their sense of self and identity to the other day.
Tell me: have you ever watched someone slowly forget who they ever were? And if it were you, would you want to die with a sense of self? Or continue to live as an empty, mindless shell?
