I couldn't be more insulted by it. I mean is the perception of peoples visions about inequality so negative there is need to try and teach a lesson here? Really there seems to be plenty of empathy already when females get screwed or when LBGT gets screwed. How is doing or preaching about doing inequality going to lead to equality? All seems very contradictory.
To address those questions in order:
There is still a ton of inequality in games, and the world at large, so yes, "lessons" do still need to be taught. It may not be comfortable, but it is needed. I've been called out for having problematic beliefs before. It sucks and I feel terrible and angry when it happens, but I've always come out of it a better person with a better understanding of others.
There is also a lot of vitriol against people who speak out against women and LGBT people getting screwed, as well as vitriol against the groups themselves, so there is still a problem.
I'm not totally sure of your angle on the last question, so I'll answer both of my possible interpretations. Preaching may not be the word I'd using, but talking about inequality helps equality because it's the only way to make sure people are aware of it. When people are aware, they can work towards equality. To the other thing I think you might be saying, one game by one company does not make inequality. The fact that this game has an unequal ratio in romance options doesn't make gaming unequal. Inequality can only exist when it is systemic; that is, when there is an overall trend disfavoring particular groups. Because gaming culture still favors the straight, white, male gamer, within societal context this CANNOT be inequality. It would only be contributing to inequality if the game industry as a whole disenfranchised straight, white, male gamers. Which will certainly not happen.
So it's not contradictory. What an equal landscape would actually look like is that you'd have a ton of different games, and some of them would have more content for one group, some more for another, and still others more for another, and only some games would have something equally for everyone. People are diverse, it's pretty much impossible to give something that pleases everyone equally when characters are involved.
It's not wrong to feel insulted and angry. That's a pretty natural feeling when you feel like you're being treated as less than others. But what's important to understand is that for women, people of color, and gender non-conformers, this is a feeling that they deal with ALL THE TIME. It's just shocking for us to experience it because we're not used to it, we can't be used to it. But what needs to happen is that those feelings should be channeled into understanding for the problems of those who are still facing systemic inequality. Because we're not. We have not been screwed. We still get more media content than everyone else combined, and one game does not change that, and one game does not mean we are facing disadvantage. And that's important to realize.
