He disrespects girls personal space and harasses ever girl he’s in contact with. He has some funny parts I’ll admit, but he is one of the worst characters in the entirety of the show
He doesn’t harass girls, he just appreciates beauty. Also by that logic you don’t like Master Roshi, Jiraya, Sanji, Brook, Meliodas, Oolong and more. Korosensei was a perv too.
He doesn’t just, “appreciate beauty” he consistently tries to touch them even after they push him away. It’s unwanted attention. He even wanted to look at the girls changing in the locker room! That is not respecting personal space. He did interships with mt lady just so he could see her and wanted to strip Midnight during the exams. Like I said, it’s unwanted attention and that’s harassment.
