Awkward

So this morning around 3.00 AM I am about to go to sleep. As I hit the sack, my roommate says, "By the way, I am gay. Hence why I care." Earlier during the week California passed Proposition 8 which banned gay marriage. My roommate was rather incised about this, but I didn't really make much of it since I am heterosexual. Anyway I was rather taken aback at his sudden confession. Personally, I don't have a problem with homosexuals and I'm not homophobic, but still his declaration was still rather unsettling. I wasn't really sure how to respond so I said, "Okay." and an awkward silence ensued. I am ashamed to say that his statement still bothers me even though I say I am not biased or prejudiced.
