you, of course, are an expert psychologist who has done many case studies on this topic i am sure-

oh wait, no. you're just some shitty asspained person on the internet.

you are using the same old tired arguments that wankgate has battled out many many times before. stop beating the dead horse. just because a character is attracted to a girl doesn't somehow disqualify them from being bisexual unless canon outright states their sexuality (and even then, closet cases exist). no amount of bitter bitter bitching on your end is going to stop people from playing "straight" characters as gay or bisexual.
