This is a rant don’t care if like or report but this annoyed me

Someone tried arguing with me my own language which they clearly can’t speak. And tried making out they checked it already and that I was wrong. And if they read this in Japanese we don’t have plural versions words, we use context to apply if it’s a single thing or multiple things. I comment on their story as I like to help people use my native language correctly and help them understand it.
