Seriously, why not just support government documents in both languages? I get that Ukraine wants to stay as far away as possible from Russian culture, but if you use both, everybody is happy.
1) Some explanation of the current language situation
Russian and Ukrainian is not like Finnish and Swedish in Finland or English and French in Canada or German\French\Italian in Switzerland were person may don't understand the other language at all or don't understand it enough
In Ukraine huge majority of population* knows both Russian and Ukrainian. Yep, some may have some minor problems writing\talking the other's language. Not that they will not be misunderstood, but their grammar\pronunciation will be weird and funny. That's all. Languages are too similar to not learn the second one when you live in a country.
* mostly morons like our last Prime Minister.
2) Russian is dominating in nation-wide mass media. Local Ukrainian media in Crimea\Eastern Ukraine is non-existent
3) There are no lack of Russian language education from elementary schools to universities there are enough Russian language options. Contrary Ukrainian language education is often not available, especially in Crimea
4) I was badly insulted more than once in my life when I asked a governmental official to use Ukrainian language to answer me. That's forcing guys like them to use Ukrainian is what they call persecution
You see they want second official language not to have a right to use Russian. They have that. They want to have a right to never use Ukrainian. Language that they despise. Language that they call an ugly dialect of Russian. Language of the cattle. Language of stupid villagers. Language of Banderas (read Fascists) and more, more and more.
They, in their heads, still live in Russian Empire as the main ethnicity and should not have a duty to learn the language of that savages they conquered. Ukraine, Baltic States. Central Asian countries, everywhere the situation is the same.
Don't you find it strange that Russian language is "persecuted" in each and every post-Soviet country?
I don't say that all Russians behave like that. I have friends, Ethnic Russians, who love Ukrainian culture and language, speak Ukrainian no worse then me and have no imperialism virus in their head
PS, Also, some ethnic Ukrainians do have inferiority complex and try to be like Russians, including shunning Ukrainian language
