When I was going to the school in Poland, the worst crap was the mandatory vituperations of Communist government propagandists. The same guys are still the government propagandists today but now they are all for free-market and globalisations in the name of supposed democracy. Now, they have views identical to the American neo-cons and are equally unpleasant to read.
The translated Russian Soviet Commie novels I had to read, were actually not so bad since they were well written.
My father escaped Poland after WWII. He married an English woman. Her brother was a labor leader in England and in the 70s sent his children to "Young Pioneers" camp in Poland for their "summer vacation."
I think that's why my father would never talk to him 8-)
