maybe, just maybe, emet is straight-coded. he may look like gay to some people but for most straight people he just looks straight.
Most characters in this game dont show an explicit proof for their sexuality. So if you want to see straight people then they look straight for you. if you want to see gay people then alphinaud (or other characters) may look gay to you.
And if you want to see stereotypical gay people or people who are yelling in our face that they are gay to feel represented (because otherwise it would be too subtle to recognize) then you may only see straight people because most characters are neither straight nor gay (because its not shown)
i mean how should it be? should the numbers be like in our world? then we should applie a rule that any character without explicit proof is straight so that we can have a natural ratio between straight/gay. Or do you want to be overrepresented to the point that every second character is LGBTQ+? We cant count 'neutral' characters as straight nor gay. so we need a LOT of additional characters that represent every possible sexuality. After that we have gender and skincolour. Hmm.... but.... gender is a spectrum isnt it? Or thats what i heard. So we need a lot of characters for all the different people in that spectrum. And every sexuality needs someone in every colour.
I'm sorry it feels as if a bit of my comment isnt completely appropriate. but its somehow difficult for me to messure that whole thing because i dont understand why people care so much about such things in a computer game. On one side i couldnt care less what sexuality someone has (real Person or character in a game) because it doesnt affect me. Everyone should be what he wants to be and in a game it just should be a good story/character/romance/friendship whatever. On the other side.... all these minorities inside minorities (i firmly believe these loud people are just a small part of their 'faction') who are crying out loud to (what it feels like) making themselves more important becames more and more annoying.
