"--Most of the misery in this world has been caused by those who figured they had a right to tell a million other people how to live. There are specific philosophies associated with this.

--We have seen one of these philosophies in action. Every society in the past century which has murdered hundreds of thousands of its own people in order to remake society in its own image has called itself socialist."

I think anyone [who is known about] has fiqured "they had a right to tell a million other people how to live". Otherwise, you would be required at gun point to force someone to write or say what she/he thinks their view of the world [or require them to write a book before they can leave a town:)].

I think can I make what you saying more clear.
Socialism is based on the idea of making all people equal. This may sound wonderful, but it's terribly flawed idea/desire. In America they said all men were created equal. This is quite different from saying all men are equal. Socialism is saying all men must be MADE equal.
Now the terrorist also want to make all people equal- they want all people to believe the same thing and all people to be muslim. And like all the socialists before them, they are willing to kill and/or enslave huge numbers of people to reach their goal.
The French also wanted all people to be equal and in the French revolution they slaughtered people until they got bored of doing this.

Socialism is very much alive in America today, but at least in America we still hold that "all men were created equal" despite Socalism's corrosive affect upon that simple but great truth.
