He wasn't commenting on your English he was simply saying that he posted that Youtube video, which was a reference itself to the picture Anwyl posted.
Basically, it's a spin off from the famous quote from Samuel L. Jackson in the movie Pulp Fiction if you're familiar with it. "English, Motherfucker. Do you speak it?"
"English, you fornicator of matriarchs. Are you fluent in its usage?" is just a spin-off, you see.
Not everything is an attack against you, pal.
