You Have No Means For Self-Defense

The most efficient tool for personal self defense is a weapon.  The most efficient weapon is the gun.  Every able-bodied person, of sound mind, in the world should own one.  It doesn't matter whether your government says or has laws against you owning one.  Most people in the world are slaves as they have no way to defend themselves and must obey their master/government.  Governments disarm their citizens because they are afraid of them as they (and they know) are lousy, greedy, power hungry, elitist, psychotic leaders.  These leaders believe that they have the right to do what they want to their subjects.  I call you subjects because only in a free country are there citizens.
Are you afraid of your government?  You should be, as in the last century, governments, after disarming their citizens, murdered 170,000,000 of you.  More of you are killed by your government than all the enemies in all the wars.  If most of the criminals in your countries can obtain guns, despite all the laws, why can't you?  Criminals are smarter than most as they don't tell the government that they have guns.  Why would you?   The irony is that the educated people should know better but they either do nothing or feel secure, but they are the ones in the most danger.  "It can't happen to me.  I'm educated."  Cambodia, 1975-1979.  "During that time, about 1.5 million Cambodians out of a total population of 7 to 8 million died of starvation, execution, disease or overwork. ... The Khmer Rouge, in their attempt to socially engineer a classless peasant society, took particular aim at intellectuals, city residents, ethnic Vietnamese, civil servants and religious leaders."  (Source:  Isn't that what the American and most European governments are trying to do today?  Attempting to socially engineer a new society?   Muslim jihadists are trying to send you back to the 7th century.  Should be "fun" times.
