This is a situation we've had time after time after time. Most of us are kinda used to it.
There is a difference between straight gamers getting twice as many LIs as gay ones, and straight and gay gamers getting the same amount... but straight gamers not getting the LI they want.
No one actually thinks that queer women are going to get more options than straight men.
I don't believe that the vast majority of LGBT consumers of video games are just "used to it" and I also don't really think nobody believes gays could get more/better options in this game. I think a lot of people would be pretty crushed right now if it was announced LGB options amounted to half as many as hetero options. I would be. I don't expect that to happen and I think many others really do not expect it either. In the same vein, I don't believe there would even be an argument in this thread if several straight people weren't scared they aren't going to get as many options, or wont have to get their exclusive pushed on an NPC, which most of the LGB players didn't want either, when they thought it could happen to them.
I'm willing to believe that you are more cynical and that you're more experienced with this situation than a lot of people are. Not everyone looking forward to the game has been following the series since before LGB options were even thought of. Most people I know never picked up a Bioware game before Mass Effect. I know a lot of people that bought the games specifically because Bioware has built a reputation as being more friendly towards the LGBT community in more recent years. Are we talking about a younger, maybe dumber crowd? Sure, but that doesn't mean it doesn't exist. I don't doubt the emotions on both sides are often genuine and that there's a lot of confusion about how this is going to play out. I think the arguing over who gets who is just feeding everyone's fears.
