Like I said many times, the issue is not that Shadowheart's personality exists in the game. The issue is that she is the only human female companion you can have.That is a huge issue for some gamers.
From what I can remember, this is the first time I see you bring up that the issue is that she is the only human female companion you can have (she's a Half-Elf, but I understand she looks the most human). I haven't seen that being the subject surrounding the female companions before until just now, it was always about behavior, "twitch streamer", contemporary character, etc. So that's a new one to me and I don't understand why this is a problem in a fantasy game with so many different races.
It does not matter what inductive generalization requires to be considered correct. What matters is that inductive generalization exists. What do you expect me to do - gather a thousand people and convince them to join this thread just to support my opinion? Fine, then you and Taril can go find another thousand who will argue with my thousand that Shadowheart is a great character. Don't you find that absurd?
I mentioned the first part because recommending learning what inductive generalization is, would mean that it would apply there and it didn't. Selectively finding a thousand people for one side and a thousand for another also wouldn't, that's not how you get proper, representative sample sizes. Garnered statistics and public awards are a more acceptable metric to use for sample sizes, which is what I brought up.
The far more important concerning that though, is that personal opinions were being put down as facts, or along the terms of "everyone/many think this", when in a conversation that's just making your own personal opinion far bigger than it is. Taril gives some really good advice on how to phrase personal opinions around facts about a character to be able to frame it in such a way that a more constructive back and forth for sharing opinions becomes possible. Leading with a demand of Larian in the title, presenting a personal opinion as a fact and ending with an ultimatum towards Larian, will lead others to disputing the "facts" you stated because they're opinions and subjective. That's why there are discussions on the characterization, background and personality of several companions and poking holes through stated "facts" by you, rather than others just giving insight in their personal experience with these characters and giving their own opinions.
