I came across this lovey t-shirt for sale on a website called Team Sarcasm Tshirts: Wielding the light of sarcasm against the dark spectrum of human stupidity for the benefit of all.
It’s unclear to me from the other t-shirts for sale what the underlying message is supposed to be. On the surface, at least, it looks as though not speaking English will result in the speaker being shot. I run into this kind of playfully extreme aggressive stance in matters of language all the time. Just one more to add to the collection.
