::::::Never in that source does it say Stewie is LGBT. "We all feel that Stewie is almost certainly gay, and he’s in the process of figuring it out for himself. We haven’t ever really locked into it because we get a lot of good jokes from both sides, but we treat him oftentimes as if we were writing a gay character" - no confirmation; notice the "we treat him oftentimes as if we were writing a gay character". This also does not confirm he is gay: "We’ve had letters from homophobic fans in the past, and I sort of relish the idea of saying, “Yeah, well, you know what? Your favorite character, Stewie, is gay". Notice the word relish? He never actually said he was gay, rather that he relishes the idea.
