Word of God emboldens people to harass others for interpreting the source material "the wrong way" WAY too fucking often. If it's not in the source material, either explicitly or even inferred, and you need to learn something from some obscure interview during a promotional tour on some exact date, god forbid where the only media outlet that recorded it isn't even on youtube and is instead on a login-walled site, it's not canon to me. Frankly, don't harass people in general, but especially not if they watched a movie where there was zero (and I mean ZERO) indication, however subtle, that the character was gay, and they viewed the character as straight. That one interview you emphatically point to where the director says "I'm open to it", or "I see them as gay, yes" when the text itself never shows it at all, isn't the gotcha you think it is, and you look like a lunatic. Try telling someone who isn't in fandom that Batman is gay because there's an interview out there (there isn't as far as I know, but same idea), and seeing how they react.
