Victims of communism was created by the CIA to spread anti communist propaganda. There are few if any facts in any of their ridiculous statements.

The only real victims of communism were Nazis, kings, and people that aided those groups. Any monument with random names from 'victims' will only realistically have Nazis on it.

It is explicitly anti-communist, but you must understand that until quite recently that was something that in and of itself was celebrated. You gotta look into the red scares. For a long time, those in power have made "communist" and "socialist" basically synonymous with "genocidal authoritarian".

If the people this monument honors are Nazis,

One name of a Nazi collaborator was found there. It's absolutely ridiculous to leap from that to "this is a monument honoring Nazis."

Millions of people were killed by Stalin. It's little wonder that a few objectionable names might be scattered among them.
