I always stick to the facts. Forget the Magyarisation terms. and now a little summary of your claim (try to concentrate):  There was full education in language X (like in Slovakia, Romania, Serbia, Croatia) and the government saw that (and this is your claim and is not true, because the same would apply to the neighbouring countires) the minorities start to lose their language. As a result it decided to restrict education in language X (you say to a few subjects, I say de-facto to 2 hours a week - but it does not matter), because there was "no need" to teach some subjects in their language (which is a sociolinguistic non-sense). This is an illogical and actually chauvinist statement. What any normal government should do in such situation (wrongly claimed by you) is AT LEAST not restrict education in the language. Secondly, bilingual schools are no minority schools. Minority schools are only schools were the full language of education is the given language. Therefore the minority schools were literally shut down. This holds by definition and cannot be subject to any exaggeration.
