You're being weirdly hyperbolic in your posts, especially saying that you not liking the trailer means that "it's never good". You aren't the center of the universe and you not liking a trailer to a Marvel movie is not the end of the world. At least that's what your posts imply to me.
Cool. Being 18 still doesn't automatically make you a genius. I did impulsive, irrational stuff at 18 and I know for a fact you did back then as well. And being through years of trauma like Peter has, being erased from existence, losing your mentor, having to save the world several times, having your autonomy taken away, and as the trailer implies, his identity being revealed is making his life for the worse, all while still not being allowed to drink...yeah, he's still young, impulsive, and immature to me, which makes me think his actions are justifiable
