As for the incidents you mentioned with Ukrainians shouting about Muscovites, you yourself write that this happened starting in 2014. That is, after the invasion of Russian troops into the Ukrainian peninsula of Crimea, which occurred in February 2014. And accordingly, the Ukrainians had the right to call for the killing of the occupiers.
By the way as regards Crimea it seems to me that you are not aware of the fact that basically Crimea has never been a part of Ukraine. This territory has always been populated by ethnic Russians. Crimea was handed over to USSR by Krushov in the 50-ies only due to the fact that it was more convenient for Moscow at that time.
It was given to Ukraine at that time only because Russia and Ukraine have always been one country and authorities in Moscow did not differentiate between Russia and Ukraine. In fact many leaders of the Communist Party of the USSR came from Ukraine.
Therefore in my opinion annexation of Crimea by Russia in 2014 is not an invasion but the US and its Europaean vassals are using this as a pretext to blame Russia for an invasion which was not an invasion as such.
Again I like your logiс and accroding to your logic I would say that in the 16th century the world witnessed an invasion of the Northern American continent by European people. This was an invasion and it must be stopped right away.
