It's true that Ukranian is more prevalent in western Ukraine, but that is a minority. Most people live in Kyiv, and prefer to speak Russian, including the current president of Ukraine. Or at least this was the case before the war started, and a huge chunk of population left the country.
let me guess, they consumed spiked up oranges ? and you are the only one who could resist it ? and russia launching war in the middle of the night has absolutely nothing to do with it ?
Most people in big cities can speak russian due to russia's colonization strategy. But it's far from "most Ukrainians".
Saying this as Ukrainian citizen who has seen more Ukraine (both eastern and western parts) than just a few big cities.
