I like the irony of that.
The Nazis suppressed the freedom of expression of several groups of people.
T T T picks an avatar which could express several things, including the possibility that, beneath the way that the EC operates and controls its member states, there may be more sinister elements, reflecting perhaps a more totalitarian administration.
It is an avatar which seeks to expose totalitarian values, wherever they may hide.
Is expresses a valuable sentiment, and reminds us never to forget that we must be wary of people who try to control our beliefs and our freedoms.
And, ironically ...
Someone, or maybe more than one, has demonstrated the totalitarian attitudes that T T T is trying to warn us about, by seeking to suppress T T T 's thoughtful and important avatar.
Totalitarianism, and the suppression of thoughts with which you disagree, or, in this case, which you have failed to understand, has once again reared its ugly head.
