The obsessive desire to own guns is a sign of being stuck in the phallic stage of development, the Oedipus complex is in full flight, and the realisation that one cannot kill their father and fuck their mother leads some to become obsessed with having a bigger penis in the false hope they can finally achieve their aim of fucking their mother. Realising this is an impossibility they turn to phallic symbols, guns being the most powerful phallic symbol their is, these poor souls stuck in this stage of psychosexual development fill their lives with as many guns as they can, they obsess over their guns, they constantly talk about them, they play with them and derive great solace from this activity. The only way for the man-child to move beyond this stage is to identify with the same-sex parent as a means of vicariously possessing the Mother. - Sigmund Freud
