People being critical of Hawk, but he has never (as far as we know) raped or assaulted anyone. He has just been extremely forward and unprofessional.
Meanwhile, if you look back at earlier chapters, it's strongly implied in several different issues that Takamura raped or at least got rough with numerous "dates". And just 10-20 chapters back we see him sneak up and fondle Tomiko while she and Aoki are starting to have sex.
All the Hawk hate (by characters in the manga, and people here) seems pretty hypocritical and misplaced.
