As for your parroting of the gun controller's "First World" talking point. Define "First World" countries for me and give your objective standard.

What you, and the gun control bigots, actually mean are majority white, mostly ethnically and culturally homogenous, northern and western European nations, plus a few Asian countries and city states with similar demographics.

Now, setting aside the very real problems with cross-cultural comparisons in general, you might note, if you knew what you were talking about, that the nations to which you refer had those same lower rates of homicide compared to us -prior- to their passing -any- gun control laws. Gun control in Europe is primarily an artifact of the post-WWI (post-Russian Revolution) period, when, there as in the US, public and governmental fear of the native poor, immigrants, often from Eastern Europe, often Jewish, and minorities, all viewed as vulnerable to enticement by Reds and anarchists, led to calls for them to be disarmed.
