Imagine the ego you'd need
To say "comrade, we're on the long march
And the killing has begun. 
20,000 purged so far. It's essential
We  know who to trust
As we march over mountains and
Learn to drink dust." The gulag,
The concentration camp. The torture chamber
All designed and working well
To convince the unwary
That 2 + 2 does, indeed, = 5.
And so save you from thinking for yerself. 
Chile under Pinochet, China under Mao,
Russia under Stalin, Saudi Arabia now.
But Germany under Hitler
Leads the way. In saying speech
Is free but only in my way. Free speech
Is dangerous, protect it at your peril,
Listen to your enemy or end up in jail..
