I guess the secondary directive of the Federation is to gatekeep having fun?
Animation isn’t for children by default. Only boring, unimaginative people talk that way about animated stories.
Star Trek has always had violence.
Star Trek has often had profanity. In another alien language sure, but we all knew which Klingon words were curses.
Does sophomoric humor graduate to senior humor when it’s subtle enough that you didn’t catch it as a child? Humor is SUPER subjective and VERY sensitive to the current zeitgeist, so comparing humor across a franchise that has been around this long seems a little absurd. Data pushed Crusher into the ocean for a laugh, that seems pretty sophomoric to me. Bones regularly joked about Spock’s racial differences, that also seems pretty crude by today’s standards.
More like working class traitor.
