This post is a copypasta so it shouldn't be taken TOO seriously, but yeah. Zenitsu is a hormonal teenager who's clingy and desperate. He's not an actual pervert.
Zenitsu's initial behavior around women was very much a result of him being groomed 7 times by predatory women. It's a realistic trauma response. I'm not saying this EXCUSES him, but it makes it more understandable since he has no idea how relationships are supposed to work. He also canonically has shit social skills and has issues with social cues, which doesn't really help (again, not an EXCUSE but makes it more understandable--and makes it important that he's apologetic when he realizes he's made someone uncomfortable and that he learns better).
He also learns better very quickly. He stops chasing after random girls in season 1/early on. After Tanjiro pulled him away from that one girl, he did not repeat that behavior. (He also hasn't harassed Nezuko at all--the chasing scene was invented by Ufotable and is non-canon because it directly contradicts the manga).
Zenitsu is indeed a realistic character--and a realistic trauma victim with realistic trauma responses rather than a Perfect Victim.
And YEAH when people rake Zenitsu over the coals but let other characters from other media who are WORSE then him off the hook it makes me want to rip my hair out. Talk about hypocritical.
Not to mention comparing Zenitsu to anime perverts doesn't make sense anyway, because Zenitsu isn't actually a pervert. He craves love, not sex.
Tbh, Zenitsu is MOST similar to Brock from the Pokémon anime, but even then Brock's behavior is still worse.
And the way people will let Tengen off the hook but will lambaste Zenitsu is BIZARRE.
Zenitsu has never done anything REMOTELY as bad as what Tengen did. The closest he's come is grabbing Aoi around the middle during rehabilitation training.
Also: while that scene (Tengen smacking Aoi) wasn't played as discipline, it's also the only time we see a Corps member do this. There are not any scenes of the Corps using spanking as discipline. Also, when the boys disobeyed Tengen during the EDA, he did not do this to them. Which makes it stand out even more.
(And yeah, Aoi's...a bit old for disciplinary spanking).
I don't hate Tengen or anything, but that whole scene annoys me so much and is wholly unnecessary.
And yeah, the cherry picking and blatant hypocrisy from the KNY fandom is ASTOUNDING.
