Here's an example - although still relative in scope, quite serious 100 years ago. ortoday if you will.

During the french revolution and the american revolution, liberty caps aka psilocybin mushrooms we're seen as the ultimate symbol of freedom.
Notice that in the Us army seal - right there in the center there is the liberty cap representing freedom, and above it says "this we will defend"
Then one could ask oneself. Now that the liberty cap is illegal - the fucking symbol of freedom itself.
Are we really free then?
And are you content being a slave?
