You really want all languages to die out and for English to be the only language left?? English, that north German discount dialect??

Identity is important. Language has close ties to a culture's mindset, traditions etc.
Killing a language is perhaps worse than killing individual people. It throws EVERYTHING into turmoil and leads to unimaginable suffering.
Bruh, you don't even know what you're talking about.
