No, I don't think it isn't. And the worst thing is that if you read the linked page they always said "Yes yes, now we are about to introduce an LBGTQ character. We're almost there. We swear this is the right time. Just a second, we're finding the right opportunity." At least it would have been better if they had been honest in their refusal to provide any LBGTQI+ representation. Instead they preferred to drown in their own hypocrisy.
I'm not sure if it's hypocrisy moreso than... diplomacy?
I don't think Berman and Bragga had any interest in having an LGBT character. Nor did Behr or Moore really for DS9. But they're all smart enough to not just say "We don't want to do that."
And... it actually is completely ok to not be interested in that. There is absolutely no reason anyone should be forced to create something they don't have an interest in creating. The responsibility is 100% on the audience to decide if they would like to enjoy that work or not. It's ok for a creator to make whatever they want, it's ok for the audience to consume what they want.
I sincerely believe that their concept of "evolved humanity" was that it had finally been established that there are only two genders and that they correspond to biological sex and that heterosexuality is the only sexual orientation.
I think that's something of a revisionist look.
I sincerely believe... they weren't think about LGBT issues at all, as to be frankly honest, a majority of people in 2024 do on the daily. I would generally consider myself an ally and support equal rights to love whoever you do and be whatever you are, but also... LGBT issues are not something on my mind a vast majority of the time. I have never, once, not a single time viewed some sort of media and thought about LGBT representation. It's something that isn't important to me personally. It's not something i'm interested in. There's absolutely no problem if a work does have LGBT representation. That's cool. I jus personally couldn't possibly care less either way.
I mean, even Data who is a robot has an assigned sex, gender and sexual orientation that coincides with heteronormativity! He can't even be asexual or agender!
Why would he be? Noonien Soong put an incredible effort into making Data appear to be human. The overwhelmingly vast majority of humans are heteronormative and are one of two genders. To make Data some non-binary, asexual being undermines the effort to take every step to make Data appear, for lack of a better term here, "normal".
Also just take into account personal perspectives. I would assume (and I might be wrong, and honestly I don't need an answer either way) that some of the people here who want more LGBT representation identify with the LGBT community. That's great. Totally support you. But you will have a different perspective from someone who is not.
I am a heteronormative straight white man. If I were to design and build an android, there is an almost 100% chance I would design it as a male. It's my experience, it's my perspective. Although I have to say I... probably wouldn't design genitalia for it, but Soong was apparently trying to get his creation as human as possible.
LGBT-identifying people are a small percent of the population today, there's no particular reason that would change in the 24th century.
Although I will give that Data seems surprisingly unaware as well, given that he actually created Lal without gender, gave her the opportunity to choose, but specifically told her that she had to choose male or female. Still, if Data's background was heteronormative, that is still his perspective and experience. Again like an overwhelming percentage of the population, they would think somebody would be male or female. Lal was urged not to choose an Andorian, given she would be the only Andorian on the ship... picking agender or some other non-binary identity would have put her at a similar disadvantage.
