“there was no difference what the building looks like in real life” as most Russians do not know its history.

That seems to be a very Russian point of view. It’s reality that’s wrong. All that matters is what you feel.

A building that doesn’t have a cross on it should be drawn with a cross on it, and pig iron will stop a bullet, it’s all the same, you just have to believe strongly enough. And of course if that doesn’t work just make wild unfounded and easily disprovable accusations. After all if reality doesn’t matter then you can’t actually be wrong.
