You didn’t read the article did you? Its not about the inclusion of a character, but about how a specific scene with that character is handled. The author claims it is completely jarring, doesn’t fit into the games setting and doesn’t even use the games existing lore for transgender people but instead uses modern terminology.

I found the article to very informative and not at all “gamergatey”.

Its points are:

• this is the scene
• it is bad
• here is exelent trans representation in a fantasy setting
• “its a BioWare self insert”
• this is how they could have handled it better
• the game is great, but now everybody will just talk about woke, so again the game is good
