Russians are not ethnically Slav......most of them are only culturally Slav....there is a big difference.
They are Slavs, alright. Russians are Slavs. It is the other questions that you in Russia have numerous ethnicities on wide territory and you have perception of Russia as of USA in ethnic sense, where whites dominates and also live many others. That is my perception of Russia.
But I understand you. Your perception is additionally colored with historical animosities between Poles and Russians and you see them additionally negative. I do understand that. WWII was missed chance for correction of relations, when Russians had chance to support Poles and not to take part in partition of Poland. But see, we Serbs also had problems with Russians in those times. Actually, not with Russians but with Soviets. Not to speak that Stalin wasn`t Russian and before him Lenin was in Germany prepared for diversion. So, in reality, Soviets were not Russians. It was twisted era.
Sure, Polish-Russian problems started even earlier. But also, what I know, Poles and Russians coordinated in respond to Swedes and that was good time.
Look, you must find scent. You must find way to heal your conflicts to the level of normal and tolerable communication. We Serbians need that from both of you. It should be more easily to Poles and Russians to be in normal relations now when are we all aware that religious antagonism isn`t key problem. Neither Orthodoxy, neither Catholicism proved to be ideal and both are equally foreign thing imposed on us Slavs.
