"How to explain it?"

Good question. I think it is normal human behavior to seek out exactly what we are looking for: Marxist hero or savior of WWII. We tend to ignore that which we don't "like" in favor of the positives we desire.

As to why the Russian newspapers are not interested, I cannot speak to that. Perhaps they view your story (and I have read it) as something contray to the agenda they have established.
