Yes it would be a nice world if everyoen thought that way, but they dont. And given the hard lessons the Nazis taught the pacifists in the 1930s and 40s, and what the arabs have taught the world over the past 100 years, it astounds me that there are any left.
The nazis/arabs would love for the world to have more fools like you, and would laugh as they shoot you and your family, and step over your corpse. Fortunately, most rational ppl in this world learned that there is a cost for freedom, for living in an open environment that allows ppl like you to come forth with your absurd ideas, and it must be defended with force from time to time.
For there are many who would gladly come to take your freedom from you, unless you are willing to fight and defend it.
