In no particular order...
- Many men are total pussies and would never consider self defense to the point of killing someone something they would do.
- Somewhat contradictally, people don't trust themselves with a gun, so therefore, they don't trust others with guns.
- Feminism. Feminism raises mothering to a societal level. Women want everyone to be protected and safe via the a motherly govt overlord. Women intrinsically desire equal outcome. That requires communism. So any means to achieve that. Like authoritarianism.
- The rise of Marxism and authoritarianism. Many people want to be told what to do. That only works on a broad scale if the people who refuse are unarmed.
- Ignorance. Cognitive dissonance. Narcissism. Lack of critical thinking skills. Inability to set feelings aside and consider things logically.
- Brainwashing. There's about 3 generations that have grown up with commie public schools telling them guns are bad. I've converted quite a few democrats from gun fear to fun by just taking them shooting and covering the $40 worth of ammo they use up.
