Monolinugal people thinking that the pronounciation of some rare words is the big issue when learning languages...
Dude, try memorizing the correct grammatical gender for every single noun or every single exception to regular declinations. And that's just for a medium-difficulty language like German.
You know how there's simple English versions of news articles? The same thing exists with German. And the language in these Simple German articles is more difficult than the regular English version.
English is THE easy mode language of the world, which is why e.g. pretty much anyone in Europe defaults to it if they are speaking to anyone who speaks a different native language. Like, if someone from Austria speaks with someone from Ukraine, they will use English.
