They were so close to having a valid point about forcibly ending cultures that are horrible (slavery culture of southern US states, nazis, etc.) but missed the mark by ignoring the differences between those aggressively violent cultures and a regular old aspects of culture like language and other facets of a regional identity. Then doubling down on trying to equate forcing the language of an invader on the populace is somehow the same as a language not being available in all public schools because there aren't enough speakers of that language in an area.
Then they ignored all of the replies that explained why the basis of their logic was wrong.
