What is banned is communist party, and not because it was communist (it was not) but because it was pro-imperialist restoration, and also just for old people who wanted to remember their youth.
I am ukrainian and have ukrainian communist friends, and they are now just as fiercly antirussianimperialism as every one I know in Ukraine. It just shows that the leftist ideas live on, especially among young people (but also their parents, who in 2014 protested for ideas of their children, when children were assaulted for now good reason, starting all the violence). The problem is that any explicit reference to communism or state socialism is very tainted. So you can see why the title meme makes a lot of sense.
Those are just reformulation of the same concept which has nothing to do with communism, just with soviet state nostalgia. Plus a few were banned after Russia’s invasion for supporting the invaders (and they are related to the soviet nostalgia kind). Anyway they lost almost all support, I was even a bit surprised that any Ukrainian I know, even Russian-speaking pro-Russia-ties people are very anti-Russia now - being invaded feels even more like an betrayal for them. Of course I do not exclude that some Ukrainians genuinely support the Russia’s narrative, but among hundreds I know personally there is not a single one.
Banning certain parties is along the same lines as Germany banning Nazi party, or would you suggest that’s oppression of freedom as well?
Clearly, I do not enjoy this division with Russia, I have Russian family, friends, colleagues. But what their state did is just not the way to do things, it damaged irreparably relations and any remaining pro-Russian political parties or sentiments in Ukraine for a generation. I rather prefer some balance and discourse would continue but nobody did more to push Ukraine away from any pro-Russian politics (even shaped as soviet nostalgia with “communist” banner) than Russia itself.
