Russians and Poles come from the same family of nations. That's a fact, not propaganda. Even Putin knows that and uses it fact in his public speeches. Call him Soviet propagandist - as ex-KGB colonel it would suit him better than me. :) Next try, please.
The Centre is a government funded propganda machine. It's 'care' is advancing causes that are strictly anti-Russian (a cusory glance at there site proves as much).
If I posted something from a Russian Government Ministry called 'The centre for Polish studies' and claimed that it was out of brotherly compassion such an agency existed I'd be heckled off the board.
