To defend that side, that's not what the ire is about (at least not from most of the people who are annoyed about it here, I think). The ire is about the poz in this game being just another tiresome symptom of a general systematic malaise in culture and society.
If (as a reasonable, liberal person) you're still thinking of this in terms of the humanistic defense of statistically abnormal people having a right to be who they are and not be beaten up, etc., then that's the way the Owlcat people are thinking of it too. And that's a rationally defensible position that reasonable people can argue about.
But that's not the way the cultural trend in the West has gone. It's gone way beyond that point. The cultural trend is towards the normalization (holding up as an ideal) of the statistically abnormal and the marginalization (public denigration and humiliation) of the statistically normal. And the saturation of entertainment product with poz is now part of that, it's no longer part of a trend towards occasional humanistic reminders (as it was, say, back in the 80s or 90s).
When people talk about "slippery slope" arguments, by now it should be obvious that the "slippery slope" curmudgeons in the 50s and 60s were quite correct: what started as a humanistic defense has become the normalization of degeneracy.
And that's deliberate, it's not an accident - but expostulating on that would be going too far afield for now. At any rate, it's an example of the rhetorical tactic of "Motte & Bailey" - you have two versions of a position with the same name, one crazy that normal people wouldn't agree with, one reasonable that reasonable people can argue about. When challenged on the crazy position, the ideologue retreats to the defensible position - "What, you don't like trannies dressed like Satan teaching your kids, do you want to kill all gay people or something?"
While most of what you said is true to a certain extent, you have no idea how sick and tired I am of the "OMG SJW AGENDA IN MUH VIDEOGAMES" crowd that spends 95% of their time in the poltiics forums or GD, and starts invading every single fucking gaming thread that isn't a straightup shooter but has a narrative focus. There will be gay couples in videogames that have, well, couples. A game that portrays governments or politics will, inevitably, discuss one side or the other. That's not an SJW agenda, thats just how narratively driven games work, and they always have. There might be games out there that go far beyond what these types of games have done for decades, and those games do deserve some ridicule for it. But there's a point where its just pointless whining that's not even accurate anymore.
There is nothing in WotR right now, that makes me think the game is trying to push some liberal agenda. Yeah, there's a fairly obvious nod towards it in the first 2 hours of the game. And then it's gone. Despite that, we have the same shitposters who whine about it in every gaming thread imaginable complaining about it in here as well, even though the majority of the game has none of that kind of content. If anything, it goes the other way. It's much darker than Kingmaker, in my opinion, and the demon-centric theme allows them to explore some much more extreme territories than wouldn't have been possible in a different setting. It's a game where during an entire chapter, the [Lawful] choice is to support slavery.
We complain about Game Journos only playing the first 4 hours of the game and judging it based on that, while the same anti-liberal shitposter crowd occasionally leaves their pol-forum hive and does the exact same thing. "Saw lesbian couple, refunded game". And it happens in every single fucking thread. Some games deserve this kind of criticism. But dear god it's fucking annoying to read the same drivel 20 times a day, usually from the same ~10people as well, especially in a game that really doesn't push the SJW agenda all that much.
So really, how much of what you wrote about actually pertains to the game that is being discussed in this thread? I agree with almost everything you said, and yet I fail to see any relevance whatsoever to this game, beyond "theres a lesbian couple, and one of the girls used to have a dick". It's minor, it's a one-time thing, it's not "in your face" but very low-key, it's not a major plot point. So I'll ask again, in what way does this negatively affect the enjoyment of the game? The solution to the issues you mentioned aren't to completely remove all references to this kind of agenda from games, or expect that to happen. It's not about supporting devs who go full-on against it, like Vavra, but about supporting Devs who simply try to be neutral about it. WotR is one such game, based on the ~140hours or so I played of it so far. The game has many issues, but being "pozzed" ain't one of them, unless your view of the game is really based on the first 2 hours of it. And then you're no better than a typical game journo.
