From the FAQ:
9) Isn't George Lucas opposed to SGR content?
First of all, Lucas actively supports full marriage equality for same-sex couples. His position and his personal $50,000 contribution to opposing Prop. 8, the California referendum that took away the right of same-sex couples to marry, is a matter of public record. For reference, Mr. Lucas' contribution is the sixth one from the top. With that, there is no reason to think George Lucas would object to same-gender romance in the Galaxy Far, Far Away.
Furthermore, if the original owner of the IP(in this case Lucas) says no to something, it stays that way. A company can not use an IP and say, "Yes, X will be there. No doubt, it's being worked on" if the original owner said it wasn’t going to happen. This simply becomes a bad business move. It's detrimental to lie about something like that. Especially to customers and even more so to investors. Not to mention that would make said company liable for a lawsuit. In short, if Lucas didn't approve, they would have never started talking about SGRs in any of the Star Wars Bioware games the first place. Besides, there is already a precedent for this content in the Star Wars Extended Universe. Which leads me to the next question...
10) Is SGR even canonically in Star Wars?
Yes! There are plenty of examples of SGRs in the Star Wars IP. In the games, it began with original Knights of the Old Republic in 2003, with the companion Juhani, who would only romance female Revans. There was also a same gender romance in the books as well, with Goran Beviin, who's husband was Medrit Vasur. Goran was first featured in the e-book Boba Fett: A Practical Man. The two of them were later fully realized in the book Sacrifice, both of which were by created by author Karen Traviss. They are officially recognized as canon by Lucasarts.
It's also been posted in the thread how LGBT positive Disney is, both in their employee benefits & park events. So no, that argument doesn't hold any water really.
