Yeah, by and large I agree. (And last week's entry required clarification for some people? Really? REALLY?!)
Would like to mention a couple of things, though.
It appears that human bisexuality, at least among men, isn't all that common. The studies and surveys cited by Wikipedia rate it as roughly between 2 and 6 percent.
I don't actually know the specifics of how Bioware intends to handle gay or bisexual relationships in ME3, nor, of course, do I have any idea how they will handle the issue in the future. But it has to be said that having every significant human male character you interact with be bisexual to give options is just lazy writing. (Or every female, for that matter, though it stretches credibility slightly less.) I'm perfectly willing to believe that the Xyrg'kkk'l are all culturally bisexual, or that elves have much higher rates of bisexuality, or whatever. I'm even willing to believe that one or two human characters (including the player) are bisexual. But until bisexuality becomes a requirement for entry into the Alliance military, storytelling and character should have a priority over being able to re-use dialogue and textures for sex scenes.
For that matter, if we really want to be inclusive, "we need homosexual options for the PC" shouldn't just mean a couple of people who swing both ways; it's perfectly reasonable, and as far as I know untouched in Bioware's oeuvre, that some NPCs just be homosexual. It would actually be more interesting to my mind to have your strangely magnetic PC be shot down once in a while because your engineering officer just doesn't swing that way.
Other than that, as long as my companions pay attention when I say "no, not interested, thanks", I'm happy to applaud Bioware taking their excellent stories in whatever direction their writers see fit to take them.
Only I'm not going to be playing them because Origin is the devil. Oh well...
