Don't really see the "double entendre" either.   He pounds his chest twice, yells, then does a double hand motion downward toward the ground . . . it is literally about "silencing" the opponents. If he did a finger guns thing (which lots of athletes have done and still do) maybe you'd have a point.  But you really just seem to be stretching here.  I don't watch the NBA, and don't really care much about James.  But I don't see any real reason to criticize him either.  I'm guessing Kyren was pleased to get the attention and recognition.  He earned it.
