"favourite lesbian couple in film"...who's forgotten on purpose "favourite gay couple in film" ?

I have no idea what you're trying to ask.  Can you rephrase it somehow?

Are you saying that because there is a "lesbian couple" poll, there should also be a "gay couple" poll?  Just because someone suggested one doesn't mean the site is ignore any other subject.  You can certainly suggest a separate one.  See the Help page for How can I send a suggestion for a future IMDb Daily Poll? . Just because I suggest one about cats, that doesn't imply anything about dogs or mean I suggest they get ignored or forgotten.

If you're truly reporting a problem with the polls feature, please elaborate.
