Sorry man but I have to disagree lol.
His whole arc (imo) is being a useless fuck (at least by his parent standars) and then proving everyone's wrong and getting a ton of self-steem when he realizes he's the only one capable of saving the day
by making the world a better place with his happiness parade after the world has gone to shit.
All that stuff is super flamboyant, but I wouldn't necessarily equate that to him being super gay lel. I felt it was more of a "everyone has some kind of strength even if they aren't able to see it" kinda thing.
