Those who have self-control do not need external control. I suspect that those who lack self-control themselves are among those leading the crusade to control others. However, this may be hard to prove.
I have family members who struggle with alcoholism. A cousin missed our grandmother's funeral because s/he (excessive ambiguity?) was in rehab. My grandfather's death was a result of alcoholism. It might seem like alcohol prohibition is an easy answer. However, this is a very superficial idea of addiction, and tobacco abuse is also common already. Moonshine and smuggling were rampant last time that was tried with alcohol, and illegal drugs today are widely available. Be honest. We all probably know a guy who knows a guy whether we partake or not. But we can all see the allure of the control freak impulse nonetheless.
I also know people who struggle with mental health issues. They choose to not own firearms, but still teach their children to treat weapons with respect instead of trying to regulate the restbof the world based on their own concerns about their own potential self-destructive urges. This is a stark contrast to the gun-grabbers who demand that everyone else be disarmed in order to quell their personal paranoia. Never mind how easily those with ill intent can smuggle or manufacture things already prohibited, or that new laws cannot address these problems anyway.
You cannot control others. You can only interact via cooperation or coercion. The former is civilized. The latter is criminal. It is strange that people understand this on a fundamental level, yet make exceptions for the State and seek to use it for their own ends. We can do better. And it starts with you. Do you choose to let go of counterproductive attempts to control, and start practicing more self-control instead?
