I’m clearly approaching this from the point of view of language as a means to communicate and connect with people, while you see language as something that has to bring you clear benefits. I went to the trouble of writing a whole ass paragraph about how Chinese is not a single country language and there are several countries worth of people outside the firewall using it. Of course no other language under the sun will ever compare to English in terms of practical usefulness, but it’s as good as it’s going to be for a second language, up there with French and Spanish maybe. You don’t have to assume everyone who disagrees is offended.
What about finger guns? Like using your index finger and thumb as a gun. That’s violent behaviour.
