then first language speakers of these will do for my point
First language is a poor indicator of whether or not the person is pro-ukrainian/russian.
Most if not all of the prominent people in Kiev regime have russian as a first language. Elensky had to learn ukrainian after he won the election. Poroshenko did not know much of ukrainian, Yanukovych (ethnic ukrainian as well) does not speak it.
People who prefer ukrainian are usually uneducated villagers. But even they speak russian rather well, albeit with some accent. So everyone speak russian there, but significant fraction does not speak ukrainian.
And language itself is not well defined. There is a spectrum which goes from something which sounds suspiciously polish which I can hardly understand to variant called surzhik which close to russian I can understand. Nazis don't accept surzhik of course.
Russian, on the other hand, is ridiculously uniform. I would say 95% of people, all over the country, speak
identical language without any discernible differences in vocabulary/accent. I am excluding native speaker of other languages who may have accents. Remaining 5% are some middle of nowhere villages.
Foreigners studying russian always note that fact. Compare it to english even in GB itself, or german, french and spanish (in Spain)
