Once they understand the concept —or at least know of it— you can reveal the convenient existence of a word for it in the vocabulary of the other language.
This is especially useful for monoglots, who often struggle with conceptualising anything not explicitly labelled by their native language.
If you are peaceful during times of systemic violence, you are not peaceful, you are enforcing the stance of the oppressors. And you do so because the systemic violence isn't affecting you or people close to you.

Communication tip:
When explaining a concept to someone that doesn't exist in their language, you need to bypass their bamboozle filters.
Don't start by telling them the word or about the concept — this is what will trigger their bamboozle filter.
Instead, start by explaining the concept.
