Guns. Phallic symbols for the sexually inadequate or pacifiers that people refuse to be weaned from? Or both. Infantile? Slow to develop?

Why was Australia able to grow up, mature and give up their guns and solve their problem with gun-related mass shootings/massacres/slaughters while the US is INCAPABLE or UNWILLING to do the same and grow up? Peter Pan syndrome? T'is a puzzlement.
