I figure when you turn on the television, you should remember that you have entered the marketplace just as much as if you walked into Tesco's. You're being sold something, and clearly, what the market wants to 'buy' in this case, is the camp stereotype, not a standard, run-of-the-mill "straight-looking" gay man. Why it wants to have this product rather than another is the really interesting question.
It's quite natural for everyone to look into the media for a reflection of themselves as seen by others, characters to identify with. When all you see looking back is a character which is meant to represent you, but is clearly a caricature, and one which you cannot identify with, irritation sets in very fast.
Those of us who are not camp, not fashion-conscious, and do not shop in BT's, do not necessarily feel 'threatened' by the stereotypical gays. In my own case, one of my dearest friends ticks all the boxes with a vengeance, and several others tick one or more. But they are not me.
No, we are disappointed that the television so infrequently reflects our lives back to us, while laying on the red carpet for 'Jack' and Graham Norton, both of whom I sometimes watch with amusement and pleasure. I realise that a flamboyant gay man is moreentertaining than a dull creature like myself, but you don't have to be looking into the box too long before you see many, many dull people characterized in drama and comedy.
It is NOT, repeat, NOT homophobic, internal, or otherwise, to be impatient with the stereotype. It is actually homophilic (if there is such a word) to not want to be pushed into a neat box for the amusement and entertainment of others.
