What's your point though? That building walls is a useless endeavour or that anti-fascism is evil becay an anti-democratic state abused the term for propaganda reasons?
If it's the latter, I hope you'll never look into the historic use of terms such as democracy, freedom/liberty or "free elections".
The point of the wall was to prevent the population of the GDR from running away from socialism; Between 1959-1960 they collectivized agriculture, this means that all the independent farmers were forced to join big state owned farms; the system did not work properly and resulted in shortages. All this resulted in the flight of more than a million citizens from the GDR to the west between 1959 and 1961; about two and a half million fled between 1949 and 1961; The east german rulers stopped this flight by errecting a hightly unpopular wall; East Berlin before the wall was a very open city - for example you could live in the east and work in the western part of the city. Now they had to justify the whole project with ideology constructs - and the ultimate trick was to apply Goodwin's law, and that was done before the invention of the internet.
