This is really the gist of it. It's not about making EVERY character (or minority) a submissive sexual pursuit, but rather the overarching choices of what type of characters are (or are not) romanceable in their games, and it's WORTH discussing.
I remember hearing the same complaint levied against gay romance options when they didn't exist in the Mass Effect games until the third title. "Oh, so you just want every character's sexual orientation to be catered to your whims? EVERYONE should just bang you, that's SO much more progressive".
It's not that. It's about taking the time, care, and understanding to craft a romance that does make sense for a character. A character like Dorian is so overtly and vitally gay that to make him a straight romance is a horrifying option given his backstory, but the point is that he's still a gay romance option, providing important representation that's well-crafted, well-executed, and without the character losing his agency.
There's zero reason you can't do that with more minority characters in Bioware games.
