I am seeing more Internet reactions about how Kurt and Blaine are role models and icons, and the writers need to be responsible about that. There are actual queer people who are saying that being put up on a pedestal is dehumanizing, including Weeds. (http://crown-of-weeds.tumblr.com/post/34166157554/ok-no-you-know-what-i-said-this-about-a). Canuck Jacq had a few things to say, and reblogged others' posts. Kurt was never supposed to be a perfect character. He always had his share of faults. Perhaps part of what's going on now is that Blaine tried to act perfect, but that was the character.
The gay characters don't need to be better than the straight characters. That's not what the show is about, and definitely not the story the Powers That Be are telling now. Sure, there are also going to be members of the GLBT community who say that gay characters shouldn't have faults, but the community is not a monolith. I like that the characters have faults. I'm not happy that Blaine cheated, but I found plausible explanations (The Velvet Rage) for why he would act that way, and I'm satisfied that he had his reasons. Self-destructive and relationship-sabotaging reasons, but reasons.
There are also viewers saying that Blaine acted out of character. If one of the producers and writers of the show is writing him, he's not acting out of character. Blaine failed to live up to his own standards, and hopefully that will be explored. There are bloggers who have been saying for quite some time that Blaine has his share of damage under his facade. All of the characters on Glee are damaged. Some just hide it better than others, and Blaine usually hid it pretty well.
Later: P. called, and we talked for about twenty minutes. Her mother has a cold, so P. may want to go down to Wilmington, Delaware tomorrow to visit with her and take her medicine. It's not that bad a drive from here. Her mother lives not far from the park that has the Brandywine Zoo in it. P. will get back to me. I like Ms. F., and I hope she's feeling better soon.
