Not saying that your reaction is wrong,just saying that it doesn't mar bioware's perfect(to my knowledge) record. If it weren't for an unfortunate glitch, no one would ever know, and the scene would make complete sense and be inoffensive to everyone who saw it.
Bioware does an amazing job, but they are far from perfect. Bioware games up until DA 2 were far from inclusive.
* There were, literally, no m/m romance features in outside of a single character in Jade Empire until DA: O. And until DA 2, there was no choice in LI for m/m players. Until there was backlash, the ME team completely ignored m/m players, but created an entire race of "sexy bisexual blue alien ladies".
* Zevran seems to not only fit into the "promiscuous bisexual" trope and it seems as if there are hints that his sexuality was encouraged/caused by his line of work. Additionally, while he is the only m/m LI in DA: O, he talks numerous times about his interests towards other women and none towards men.
* Isabela also falls close to the "promiscuous bisexual" trope.
* Serendipity, the only trans character is a sex worker. Although the devs have indicated that she's supposed to be more of a drag queen, it doesn't mean that the "lady boy sex worker" thing isn't a bit questionable.
* Wade is incredibly stereotypical in his behavior. That by itself isn't a problem because it represents how many gay men act, but when he is one of only two confirmed gay men in the games, it's, again, a bit questionable.
Now, all that being said, I don't have a problem with what Bioware is doing because: 1.) It's one of the only companies that actually addresses the LGBT community at all; and 2.) the devs have been awesome about coming onto the forums to ask questions and use those responses to help inform their future decisions. I'm sure it will only get better from here and it's all been appreciated, but I wouldn't say that it's been a perfect record up to now, either. And I say that with nothing but respect and love to Bioware.
