Said Civil War did result from the multicultural differences represented by the multilingual problem.

The specific cultural difference in question was the question of slavery: said cultural difference was addressed on both sides by English speakers (most non-English-speaking folks didn't give a s**t about it until the draft board told 'em to get on the train).

1. The post in which you replied to asked for the identity of a multilingual, multicultural nation. That America was multicultural at that point, which you seem to admit, negates your attempt to use America as an effective example.

2. The language differences were quite important as they tied into the cultural difference. The urban areas more likely to have non-English speakers were in industrialized regions in the North that had different cultural and economic interests than the agrarian South.

3. Again, this argument assumes you are correct that there were indeed "very large tracts of this country that didn't speak English until the advent of compulsory public education." What were these "vast areas" and what were their percentage of the population?
