"That was then and this is now" is not how it works in such transitions (and after such wide-ranging power and influence of the far right, and such bad blood from the murders and torture). Not any more than it worked for the blacks after 1865 (or 1964 for that matter), to give an example from US history.
Hell, it took decades even for post-WWII Germany to shake the ex-Nazi-high-ranking influence in its politics, media, finances, and so on, and the Nazi rule was just 12 years, and they had far more horribleness and more shame as a motive to stomp out those elements after 1945...
The same has been true in post-Franco Spain, and any other place with such history.
Keep in mind Germany had to deal with the Soviet threat at the same time. Sadly, the communist influence there will take a few more decades to stomp out.
Things seem to have worked out fine for Central and Eastern European post-communist countries. Also Portugal, Greece.
