Canonically, he's none of those things! He's just a magic man. With no actual established sexuality. I've seen plenty of straight, cis men and women you would swear are queer without knowing them - I had a roommate with every 'Lesbian coded' thing you could think of, but she just... liked a lot of the same fashion and styles, etc and kept getting mistaken for a gay woman. A male friend of mine thought he might be bi, and decided he wasn't after testing the waters, but often comes off to others as gay/bi... but he's not. Don't judge a book by its cover - whether the person is real, or fictional. (I thought we all knew not to assume people's sexualities by now, but... here we are. This same kind of shit made Heated Rivalry fans act like childish pricks - fandoms love to assume and demand sexualities, and engage in media fandom in unhealthy ways.)
That said, this is fiction. Emet Selch does not exist. He is 1s and 0s. He cannot be gay or bi or ace or trans or anything else anywhere but in your head. So go buck wild, design the fictional character however you personally want to see it, because he's not real, and you can do that! - and remember that fandom was made so that we could all celebrate loving a certain piece of media together. Not to argue about what kind of queer label Spock or Kirk is - each person is entitled to THEIR fiction and head-canon, and attacking them over it is the epitome of immaturity... you're playing pretend, and fighting over the make believe character?? Do you know how actually, literally childish that is for grown adults?? 8 year olds play pretend on the playground and don't act like this.
And then to take the childish antics so far as to attack whole queer communities in real life is filthy beyond belief. Bi people exist, hi... hello. We like lots of different genders and gender presentations - 'bisexual' means we like "two or more". We're here, we're queer, and we deserve some damn respect and acknowledgement. (And don't be shitty to the Lesbians either?? What a weird, low blow comment that was to see in response to this.)
Every day, I'm glad I left XIV, the toxic positivity, and unbelievably unhinged community that cannot separate fact from fiction behind... but shit like this is a good reminder when I think I miss it.
tl;dr Emet Selch is fictional, so he is whoever and whatever YOU want him to be. He doesn't belong to anyone but SE - and we should be excited to hear about others' ideas and interpretations, instead of "I head canon him as gay, so everyone else in the world is just painfully stupid." That... is a person struggling to separate fiction and reality - Emet isn't real, and you're much too invested in 1s and 0s if you're attacking real world ppl and communities over head-canons.
Live and let live. If you hc him as gay? Great! That doesn't hurt me at all, if I'm someone who prefers to see him as trans. Or bi. Or just 'queer' as a broader label, since he can body hop and all that - those can all co-exist. But the second you start attacking real people over fun, IMAGINARY PRETEND PLAYTIME, you're deeply in need of some time away from fiction, and back in reality.
