I guess it depends on who makes it and what relation you have with them. Of course, any inappropriate joke w/violence isn't good, especially since you added "truly" so in a way, depending on what it is, I'd just look at that person like, "dude, wtf?" ya know. I'm not exactly a sensitive person nor do I give a shit when someone offends someone by "addressing" them with wrong/right pronouns, not until someone actually gets hurt.
