My problem: Ian often has relationships with women (at least in the U.K. version). In the sixth season, he settles down to a long-term relationship with a woman. Asked if he's bisexual, he replies "No, I've just found the right person." Apparently every man, gay or straight, is looking for the Woman of His Dreams.
other examples can be found in Party Monster, Transamerica, Noah's Arc, Chelsea Boys, and of course Will and Grace). Instead of stating that the characters are bisexual, producers insist: "No, they're gay. It's just that, like all men, they find sex and romance with women infinitely superior." A blatant Uncle Tom attempt to demean, diminish, and erase same-sex desire.
But Cameron Monaghan doesn't seem to have a problem with it. He previously played a gay teenager in the short Two Boys (2010).
Still, the actor doesn't seem to be very savvy about gay identity, implying in an interview that his character "made the choice" to be gay.
He is so often rumored to be gay that he recently "came out" as not-gay on Twitter: "No, I'm not gay. Yes, I play a gay character. No, the question should not be relevant." Apparently he is not familiar with the terms "straight" or "heterosexual."
