Look what happened in Ukraine. Among neonazis, they supported this:
Ukraine's 2017 education law will make Ukrainian the required language of study in state schools from the fifth grade on, although it allows instruction in other languages as a separate subject,[65][66][67] to be phased in in 2023.[68] Since 2017, the Hungary–Ukraine relations rapidly deteriorated over the issue of the Hungarian minority in Ukraine.[69] According to the New Europe:
The latest row between Kiev and Budapest comes on the heels of a bitter dispute over a decision by Ukraine's parliament – the Verkhovna Rada – to pass a legislative package on education that bars primary education to all students in any language but Ukrainian. The move has been widely condemned by the international community as needlessly provocative as it forces the historically bilingual population of 45 million people who use Russian and Ukrainian interchangeably as mother tongues to become monolingual. Furthermore, the large minorities of Hungarians, Jews, Poles, Tatars, Gypsies, Romanians, Caucasians, and Gagauz generally speak and receive some formal or informal education in their own national languages, all of which will be adversely affected by the new draconian language statute.
Also:
Lviv Oblast Unian reported that "A ban on the use of cultural products, namely movies, books, songs, etc., in the Russian language in the public has been introduced" in the Lviv Oblast in September 2018.[71] Critics[who?] called the law ill-defined, illegal, and unconstitutional, and a successful January 2019 court challenge by the Chuhuiv Human Rights Group was dismissed on technical grounds in May, and could lead to a complaint before the European Court of Human Rights.[72]
They tried to ban the public usage of Russian in Ukraine.
That's a little step towards fascism.
