Totalitarian systems were not established as an effect of some “wrong” ideas. They appeared because some ideas were not challenged. It happened when the “politically correct” majority that proclaimed these ideas as the correct ones, decided that freedom of speech applies only to what they believe.
 

It does not matter what any idea calls for. What matters, is that the idea is exposed to the public scrutiny and critique. And it is enough to keep the society in balance. However, when the “politically correct” majority silences some of the controversial ideas, the balance is lost. And the suppressed minority becomes oppressed by totalitarian regime. 

Because... 

We think. 
We communicate what we think. 
We try to do what we think. 

All of the legal systems try to limit what we can do. This is for the well being of the majority. 
But, we still can communicate what we think and have a chance to change the law so we could do what we think.

So, we are like dead.

And then we die for real. 
We die in the riots, we die in the wars, and we die fighting. 
We die in refugee camps, and we die on exile. 
We die discriminated, and we die in poverty. 
We die with a written note, or without. 
We die quietly, we die unknown, and we die anonymously. 
We die in jails, and we die in executions. 
We die mentally ill, we die from overdose, we die from accidents. 

We die trying to say what we think.
