Following the US backed 2014 coup of Ukraine's elected leader, in part for not being anti-Russian enough, there were mass protests and demonstrations in Crimea against the rabidly anti-Russian (both the country and Russian speaking populace that makes up much of Eastern Ukraine) incoming coup government. It held a referendum on independence, which passes with massive popular support. Russia was asked, by Crimea, to guarantee it's security when it was clear that the coup government of Ukraine would not accept their independence, and as a result there was annexation. Meanwhile, the Ukrainian coup government was also engaged in a brutal civil war against the Donetsk and Luhansk oblast regions including daily shelling and empowering neo-Nazi groups to commit murder, torture, and terrorism against the people of those regions.

Literally all of this is historical fact that you'd know if you read literally anything on the subject, even a Wikipedia article, and is acknowledged even by those who support thr 2014 coup and subsequent Ukrainian governments.

You're calling people delusional while not even knowing the first thing about actual historical fact. Go do some reading.
