Well, everyone can read the Wikipedia pages and their references, and make their own minds. Our views are so fundamentally different that I see no reason to continue discussion.
'Banning all books on Lithuanian language' and 'banning books in Lithuanian language written in Latin alphabet and encouraging transition to books in Lithuanian language written in Cyrillic alphabet' are different things.
Former would have had a goal of discontinuing written Lithuanian language and the latter had a goal of switching Lithuanian language from Latin to Cyrillic alphabet.
Misrepresenting the latter as the former is a lie.
The only thing important part is “these books are banned” and “these books are encouraged.” That you don’t care about the specifics says more about you than the ban.
