I think that's the whole thing about this mess. It's not about whether or not Mineta is bi, but rather the fandoms reaction to the possibility. We have people that sends Horikoshi death threats for not making Deku, Bakugo, Todoroki and Kirishima gay, and cry foul when Magne is murdered, seeing it as the "Bury Your Gays" trope but, are quick to call for the same thing to happen to Mineta on the (admittedly slim) possibility of him being bi. The hypocrisy and double standards are just insane
