Probably ignorance.

說 would definitely be better. 說話 is always intransitive (話, which means "speech", acts as the object of 說 "to say").

Good to know. My Chinese is shitty and woefully insufficient. I'm decent at writing it though!

Japanese
I saw there is already a translation in Japanese but I think that it should be 日本語で話せ instead of 日本語を話せ... I'll wait for a native speaker to solve this.

Nivkh
Here I want to try to provide also a Nivkh translation. The only thing I'm not sure about is the usage of the verb "p'ur-" with the name of a language, maybe there is another more appropriate verb. I'll look up for this!

ɲi t̩'i iřt̩p'anp'arad̩ra. ɲivx p'urja!

Usually Nivkh is written using a modified Russian alphabet but I prefer to write it using the IPA alphabet. This is just for my own comfort.
