I'm not gonna have any slanging matches so please, nothing personal is intended!
Regarding camp as a construct I think it depends on how you perceive it and to what level it goes to. Balance is the key thing here.
It can be a way to appear lightweight and less threatening. On some level that may work as a way to get ahead for some industries even behind the scenes- as a marker to set them apart from others or as a way to feel more special on some level, branded as the 'happy-go-lucky gay gay'. I think this may be what the OP meant as an 'Uncle Tom' figure.
My issue is if this is the main and only thing one forms their identity around. To the extent you become a male version of a brash bimbo i.e Jordon/Jodie Marsh(Glamour models for those overseas!). Excessive full on behaviour however it manifests itself isn't exactly celebrated in wider society.
But back to the main point about role models in the media. Although the media does have a big influence on shaping our views, and does have a role in representing more balanced characters and viewpoints but it can't be the sole source. For the most part it is there to entertain/make money, conveying empowering messages 24/7 isn't on its agenda.It's too difficult for them to be all things to all people.Although some gay magazines appear to be less confined within a gay box editorially in terms of the articles. They still revert to 'type' through branding via lifestyle articles and specific adverts for upscale fashion, holidays, accessories, interiors, restaurants etc and the more obvious sexual sceney stuff.

Indirectly you're given a vision of the ideal gay man. His income level, appearance, ethnicity, social interests etc. They can't critique the consumerist elements too much as advertising is a big part of its revenue and their clients wont advertise in places where they don't think will make them money!
The key thing is to work towards being a decent human being that happens to be gay. Take traits from different sources and make them work for you as a healthy fully rounded individual but accept you're always learning. ( I hope that isn't too in depth)
