my opinion
when you look at the political scene in eastern europe, the primary way communist parties try to gain support is to appeal to disaffected 40-60'ish people with some form or another of "ostalgie" or "soviet nostalgia". there's nothing principally wrong with it, but i feel it is way too oriented towards the past instead of the future. "look what we had" is good for some but ultimately it isn't enough to build movements. you see communist parties who still refuse to recognise the collapse of the ussr.
my gripe with this isn't that i disagree with them ideologically or morally, as the liberals do, the problem is the union is definitively gone. there is no hope of restoring it, there hasn't been for nearly 40 years. we need to start from the beginning again, the old structures have been fully dismantled and the union will not return, not in the next few decades.
this is ignoring the fact that this is really only appealing to.. well.. 50 to 70 year olds. we should focus our agitprop and work towards the youth of our countries instead of a group of people who ultimately will go "extinct" soon.
sorry if it came off that way, care to explain why?
