Despite my own misgivings about American conservatism, I don't think it's correct or appropriate to suggest that they would prefer for suicidal people to shoot themselves.
I didn't mean to suggest such a thing; what I mean is that if someone in the US wants to end their life, they can (and I'll skip any macabre details about how easy it is) do so very simply with a firearm - I believe it is the most successful method. I just find it rather dissonant that the belief that weapons should be so easily available pairs with a supposed respect for life.
