Taking into account that there are 4 times more Russians on this planet than Poles, and that it was Russians who established the first communist paradise your statement doesn't seem to be very credible.
In fact some of the most horrible were Polish.
You mean Iron Felix? Felix was Polish only by birth. He renounced his country early in his life and became Russian revolutionary. He was Polish to the same extent as Hitler was Austrian, that is not very much. Even worse, he was not considered Polish even by his contemporaries. If he himself thought that he was Polish - only God knows.
You mean to tell me that all those years of the Polish Communist state, it was really Russians in Warsaw speaking Polish? Yeah...
C'mon now. As for more Russians than Poles being commies so what? What matters is the ratio not the actual numbers.
Again, it is the future that matters. There are many negative qualities of the secular west that need reform. Russia and Poland can together form an alliance of moral uprightness shall we say as a bulwark against the tendency of the west to deteriorate into secularist immorality.
