This had turned into the new Fight for the Love thread

In any event, I find it funny how some people are saying "but Kaiden was supposed to be bi in ME1!!!!! He had romance linez but Bioware took them out!!!!111"
Yeah, they took it out. There is no in-game, factual evidence that Shepard (male) is anything but a heterosexual male. Has he had the opportunity to (and in many playthroughs for people, experience) a love affair/flirting with several different women: Ash, Liara, Shi'ira, Miranda, Jack, Kelly, Shiila, Parasini (could be missing some). Does he ever even flirt with a guy? I must have missed it in all of my playthroughs. You would think, wouldn't you, that if Bioware had ever intended to truly make Shepard possibly bi/gay that they would have at least hinted at it in the first two games?
"But my Shepard didn't romance any girl in the first two games, so there's a chance he's gay/bi!" How am I supposed to argue against this kind of testimony?
I know I will be barraged by about 25 posts in like 3 minutes, but I don't care. Male shep shouldn't be gay. or bi, whatever.
