Here we have yet another manipulation from a poster that pretends to be pro Ukrainian. But whose purpose it is (obviously) is to spread anti Russian sentiment. There are government-funded organisations that engage in this sort of activity on purpose. I recommend you examine this persons posting format, their templated-responses to certain topics and a hyper-repetitive nature of their posts. Compare that to any other poster here (including myself). Or anyone else that posts here regularly.
I'll let you decide whether this person is paid, or not.
Here we have more emotionally polarizing adjectives as well as false claims, that have been addressed plenty of times before.
What this person refers to as "the Kremlin", considering the time-period that this person is addressing is also known as "the Soviet government". I am not going to bore you with the intricacies of how the Soviet government worked exactly. You can research that on your own. Let's just say that the Soviet government included people of all sorts of nationalities and ethnicities. Including Ukrainians.
However the main reason that this poster keeps talking about the Kremlin is because they want to associate the government (and their decisions) of a country that no longer exists, with the current government of the Russian Federation, that has less in common with USSR than modern Ukraine.
Now brace yourself for yet another portion of anti Russian "truth" that his poster is undoubtedly going to reply with, as this is exactly what their purpose is. Spreading anti Russian sentiment (hate) at every opportunity they get.
