Censorship is always proof of the weakness of the censor. The inability of censors to allow rational consideration proves that they are wrong, and vulnerable to being defeated. It's always a precursor to violence, because people that can abide facts always defy censors and those facts actually exist and are learned despite censorship, and the censor inevitably resorts to violence to retain their power.

Reality exists, and the fact that censors can't retain their power if reality is known exists too, and eventually censors are disempowered. Since they inevitably resort to violence, they are destroyed by that very violence in the end as the reality they are trying to hide because it will disempower them does so.

Bukowski is right. Censors are pitiable and the cause of their own destruction.
