Is the Patreon version like that? Or I guess the version on here? I was going to argue that censorship would imply that the content is missing, because it isn't in the Steam version. Incest is just a toggle in the settings menu, I didn't have to do any "after market modifications" to make it available.
There is also a run-once screen when you first start the game asking if you want it on or not. I don't know how to open the game files to find that image otherwise I'd put it here too. Strangely, and I think your side would agree with me on this, it is also part of the menu on the bottom:

Isn't that kind of weird? It seems like thats a fire-and-forget setting, who needs to be able to toggle it on and off at all, let alone frequently enough to want it on the menu bar?
Anyway, all that was just to point out that we might have been talking past each other on the censorship argument because our game versions seem to be significantly different on this issue.
I almost agree about not having to romance her, but the issue doesn't affect just one character, its four. The two MILFs and their two daughters. Thats 40% of the LIs, so if the incest wasn't toggleable then the game is that much less attractive to those who don't have the kink.
Also especially because Shortcake is one of them. 
...Also the story revolves around sister/childhood friend. Her character sheet entry doesn't even have a heart to toggle on or off her path with. So she's not really an optional LI, you either gain points, or try to balance them, or purposely drive them into the negatives. You can't opt out like you can with everyone else.
Sure, those lines look out of place in the non-incest version, but who cares? Is that part of the thrill, the pearl clutching by the other characters? I don't mean that to sound... judgey? Just don't understand why it was mentioned, because I just ignore those lines. And all the hemming and hawing of the MC's "oh but I can't!" train of thought, thats what
skip is for. Incest is such a pervasive kink in AVNs that you can't get away from it. Games that have absolutely no need to put a blood relation in it do so just to get that tag. So I'm used to ignoring all that.
P.S. I think I said this in this thread when I first played, but that MC needs to get a fucking CAT scan or something, he's been knocked unconscious like at least once a week so far.
