Wow. Even if you’re solely interested in LGBTQ representation, wow. Taash is absolutely AWFUL representation, specifically. Abrasive, not well integrated into preexisting lore, aggressively modern in presentations for a lot of reasons (their choice of nonbinary as a self description being only one).
For contrast, look at Dorian in Inquisition. I rolled my eyes a little at his loyalty mission, because it was kinda preachy, but it was so much better handled and integrated. He never used a modern term like Homosexual, he just said that he preferred the company of other men.
His dad, despite doing the magical equivalent of trying to make him straight with a course of electroshock therapy, was presented with a lot of sympathy right from the word go. You could tell that both father and son regretted that they were on poor terms even as Dorian (justifiably) tore into the guy.
Was that too much nuance? Did people complain that Inquisition was giving someone a pass for homophobia?
