The truly scary part is how many people believe that they have all those answers and want to impose their ideas on all the ignorant people who don't have all the answers.

Today, Sanger and Rand are viewed with the same enthusiasm as Hitler.  And only because he carried the idea of eugenics to their logical conclusion.

And today, we have zealots who have all the answers and those on the other side (pick a Party) are demons and ignorant for not wanting the "Party" to do what is obviously the only solution to all our problems.

Those are the truly scary people.   

Because they are doing it "for our own good" and with the best of intentions.
