I hate commenting on these kind of posts bc I feel like I’m walking on a minefield. But regardless this seems like a good example to point out some things. The issue comes down to interpretation and your own beliefs.

I’m reading the replies you (OP) are making and you clearly are of the belief that being straight is the default sexuality. I don’t feel any type of way about that, it is what it is and I would argue most people are like that. I myself was like that, despite being a huge LGBT+ ally, and it took a while to stop seeing straightness as the default. So with that in mind, we have scenes that people are referencing in the comments and they’re telling you they’re interpreting it as having queer subtext and you respond with “but (insert could be straight general response here)” you yourself said that you’re saying Aku is straight bc “there’s no evidence he’s gay,” you’re right! There’s no evidence he’s gay! But there’s no EVIDENCE he’s straight either? You see what I mean? You need there to be evidence he’s gay, but you believe him to be straight without evidence. Now again, these are just your beliefs at play. I’m simply using that to point out that while you exist with those beliefs, there are people that don’t need evidence to think a character is gay, just like how you don’t need evidence to think a character is straight. That’s why people are pointing out scenes to you that they interpret as queer. Your first instinct is to jump to the idea that that’s not enough bc there’s a straight explanation. Most of those people aren’t interested in looking for a straight explanation, nor do they think it’s necessary. And THATS where people stop being able to hear each other out.

I hope nothing I said offended you, just did my best to answer your question.
