I know this sounds pathetic to people, but to a lot of people it is a niche that they want to be explored. It is a "need".
They want to engage in escapism, or self-insert stuff, circled around "waifus". Either because is fun, or because they want to cope with certain things in their life.
There's quite literally nothing offensive about it.
And I know that these same people would be okay with something that is meant to be pleasing to LGBTQ people. We have seen it with Hades 2 ("Safe Horny") and Baldur's Gate 3 (Just unapologetic horny).
They want that niche too, for them. And that's FINE. Just like is fine for straight people to want that too.
I'm completely unbiased here, because I'm in the camp that is excited about Metaphor: ReFantazio. A game that supposedly has no waifu or horny/romantic self insert content. I don't like waifu shit, it's mind-numbingly boring to me.
But the argument against the fan service of Snowbreak screams inconsistency and biase.
If you are gonna take issue with fan service, go hard and deep about it. Don't be against the shit that doesn't make you dick or pussy wet, and okay with shit that does.
