It's not a one-time thing. The lesbian couple are the most prominent NPCs outside of part members until the end of Chapter 3, trans-girl is the one who gives you all the main quests. There is an unique animation of them hugging once they meet each other. Then they discuss interior decorations during the act-ending cutscene. It's very much intended to be prominent and noticeable by everyone. My personal theory is that they wanted to make sure braindead journos notice that there is gay representation in the game.
Most prominent NPCs? Give me a break. Both are complete non-factors in Chapter 4, in Chapter 3 Irabeth gives you 4 quests at the very beginning in a matter of 5 seconds, and then you turn them in with her eventually as well. Besides that you have 1 project for her, which pertains to her position in the army. None of this has anything to do with her being gay. You interact more with the Council members (of which they are not a part of, by the way), or individual NPCs like Ciar, Horgus, Nurah or Seilkind or whatever his name is.
Anevia barely shows up except for ~10seconds for the Dragon Hunt Quest, where she refers you to Nurah (which plays a more prominent role than Anevia+Irabeth combined), and Anevia also shows up during Cams Companion Quest, where shes totally fine with you keeping her secret and letting her continue to murder people to sate her bloodlust. Super SJW, you're right. Suture is a more prominent character than either of those two, and he actually has main-plot relevance. Anevia and Irabeth do not.
Also, there are 2 full-time healers in the game, the softest gay black man ever born or bisexual tumblr incarnate, if you're not playing a healer yourself you need one of them. They will both hit on your male PC until you explicitly tell them to fuck-off.
You mean the soft black dude with gambling issues whose anger you can fuel to the point where he beat someone to a pulp with his fists? Ah yeah, he's such a cheerful character, and you can't do any harm to him either. Despite, you know, killing him from the very start, or if you so choose, torturing him every chance you get, including being able to raise his brother from the dead on the Lich Path and constantly taunting him and his shitty beliefs. Also, that's typically how romances go. People court you unless you tell them you're not interested. If anything, I'd say its a fairly negative portrayal when all non-hetero companions come off as super horny, pushy and needy.
The fact you're just omitting Camellia and Ember, who are both Divine Casters, just to try to make your argument stick is very showing, however. There's like 6 different divine Casters in the game, 7 if you count Staunton. Meanwhile we have 2 Arcane ones, and one of them is a furry (and even that revelation lasts all of 2 minutes and after that you can just have her be a human at all times anyway). But sure, one of the divine casters is gay so thats totally pozzed.
It's not like people are talking about minor details, people are discussing things that were made to be noticed by as many people as possible. The only reason why wokeness didn't completely ruined the game is that long stretches of the game are dungeons with little to no dialogue. Sossiel is a terrible character and probably one of the worst gays characters in media in general, but he's bearable when the only thing he says are order responses.
Sosiel is actually pretty okay when you decide to turn him to the dark side. You can belittle his faith and beliefs every chance you get, and while at first he only falters occasionally, he eventually becomes a very different character. But he's still gay, so I guess most people in here would still have a problem with him.
To me, SJW writing that would annoy me is when it's in my face constantly and when the characters portraying said agenda would be either unkillable, or have no bad qualities to them/bring the topic up constantly. That's not the case. Their romance is a non-factor, to the point where you can hit Irabeth in the face with demonic Rage and give her a nasty scar and her GF is standing right next to you, barely complaining. Once Chapter 2 is in full motion, there's no hint of their romance whatsoever anymore. But to know that would require people to play the game for more than 10% of its content, and it would defuse many of the "game is pozzed" claims.
But hey, maybe people here simply don't know what the source material is like, and how Paizo went as far as to state that all Iconic characters are to be considered bisexual unless stated otherwise. Compared to the source material baseline, I simply don't see WotR as the devs trying to push any specific agenda at all. Even without that background knowledge, the game pushes topics like slavery, offers the option to have someone violently gang-raped, support cannibalism and similarly horrible concepts, with some of them being considered "lawful" options due to the locations those situations happen in.
