I'm all for giving people hope and certainly have nothing against telling stories with happy endings. I don't think I have read many of the articles in question but I think I know what you mean by glamorizing. It is like the movie based on a true story where the director can not resist making something look good when it really isn't. For example, a scene where someone jumps off a tall building often shows a gracefull dive and possibly an expresion of peace comming over the character's face. It almost never shows the body hitting the ground. Another example is a low buget tv movie about eating disorders or alcoholism. The person is shown running into the bathroom to vomit but the character never looks malnourished. The stomach acid never destroys his teeth. His hair is falling out in clumps yet he always has a full head of hair. The suffering is depicted as something with a beauty of its own. In reality these people die slow and painfull deaths with no makeup artist on hand to make them look good.
The problems of gay people are probably presented in the same way. It is as if someone wants to say, "Look, he's gay and everyone hates him. Doesn't he look brave and handsome as his classmates beat the crap out of him!"
I think that if you want to tell a trajic story you should not air brush it. If there was no happy ending do not make one up. If it was not a prety scene there is no reason to change it. Some times life actually does suck. There is nothing wrong with admitting that.
