Wow, you really are full of it and quick to look down on others. You were so eager to assume they want to fap to her, without realizing Bugpope wasn't even the one who wrote that original post and has no need to defend it or answer your question.
And you were so quick to assume I am unable to follow a simple conversation you didn't even realize I'm arguing against a conjecture, not an individual -- and thus it is a matter of no consequence for the sake of my argument whether a supporter of said conjecture is the original author or someone who jumped on the bandwagon.
By the way, are you also of the persuasion that Saijou Nagisa is romantically or sexually interested in boys? I'm asking because, even though you were very quick to take HellAQA's side and attack me, you haven't provided any evidence either. I'm still waiting for someone, anyone, to explain when and where our Nagisa showed by her words or actions to have an attraction to the opposite gender. All the replies so far have been personal attacks, no factual proofs or elements of corroboration at all.
Whatever you like it or not, it is a fact she wanted to confess and date a guy, so unless it will be elaborated on more later, as far as we know, she is capable of being attracted to both guys and girls, which by definition make her bi.
I'm not convinced. She wrote that letter to a boy, yes, which means we do have evidence that, unlike Nagisa, she was willing to try heterosexual dating. She wrote that letter, then misplaced it and ended up dating a girl -- and, so far, I haven't detected even a hint of a shadow of a feeling of distress about the mistake. In fact, in her own words: "By the time I got back home, I didn't care about Kobayashi-kun at all. All I could think about was Saijou-san." Seriously? She forgot him in a moment, just like that? No heartache over the boy she's supposed to like? No angst? No brooding? No agonizing over which one to choose? This doesn't read bisexual to me. It reads more like: "Girl thinks she must get boyfriend because societal norm says it's the thing to do, but then finds she's gay and happily casts away the dumb notion."
Tho I do understand (unlike with Nagisa) if, in this case, some readers disagree.
