correct me if I’m wrong but I’m pretty sure the reason steve doesn’t like teenagers being heroes is because being a teenage superhero is literally what got bucky barnes killed/turned into a brainwashed cyborg assassin and that kind of messed steve up for a while
also a. bucky didn’t know steve when steve was younger and b. steve is much less reckless in 616 which is the universe where the young avengers exist the mcu does not have the young avengers respect the multiverse oh my god why is this bothering me so much
