It is huge topic, here in my (wider) region discussing “good and bad sides of communism” can still be very dramatic.
Because people live very hard today ( past war, unemployment, poverty etc.) lot of folks have tendency to kinda remember the communism like “good times”.
In reality it was time when you could not do what you wanted, or speak what you wanted, no liberties, secret jails etc.
Real life and romanticized imaginations are two different things.
