It may seem like there's a more of an open attitude in this series, but other than Johnny's flirting with Gary you'd never know it for sure from the live competition broadcasts.
If Sami hadn't said she was a lesbian elsewhere few viewers would be any the wiser, and when judging her a few weeks ago Kelly said something about how she'd really connected with her song, and that it must've come from an experience with a man.
Likewise Marcus, who originally was shown emotionally responding to a newspaper outing, but neither confirming nor denying it, has since been made to dance with/gyrate next to females, and lyrically sings his songs towards an opposite sex love interest.
Craig has confirmed he's gay in a video which hasn't been shown on TV, after Nu Vibe accidentally outed him in one of their exit interviews. But on the X Factor lives he may be taken for straight by most viewers.
The reason they play it that way is the traditional worry of losing votes.
I'm afraid it's up to Johnny to openly fly the gay flag. I hope if he appears as Sarah Lee he'll sing Mad About The Boy and sling his suspendered leg around Gary's neck, á la Goldie.
