To me, something worse than weak "geek chic" humor is people bemoaning the tragic personal injury that this has done them....
...I guess this new wave of "stuff" doesn't bother me because I never felt like I needed to have my likes and hobbies protected from the outside world, or that there was anything inherently superior or righteous about them. And having someone compare me to Leonard from Big Bang Theory (lightly or as an insult) is better than a cowboy boot to the liver or having my teeth broken by a class of '93 ring any day of the week. That, and my whole family lives by the belief that the best comedy comes from our own insecurities...so maybe it's just some aberrant ingrained thing for me that keeps me from feeling debased or abused by rampant inaccurate pop culture simulacra.
So you had it bad for being a geek? Try being a geek AND gay in a deeply catholic town in a deeply conservative town within a very conservative family.
We have all had our fair share of s*it in life, so I know how you feel. That doesn't mean we should put up with more because the new one is less painful than the old one. Do you think children at school won't be bullied and name called because BBT is out there? You really think children won't be mocked - and some beaten up - because they wear a Sheldon t-shirt? Or because they wear a geeky t-shirt?
It might be less painful to you, but probably not to them.
The fact that there are sitcoms that have been well written (and yes, I do believe every series should strive to be as good as Blackadder, even if they can't get that high up) shows that any series could be well written.
I understand for you being insulted is less painful than being kicked. I just don't understand why we even have to be insulted.
At no point I have also said my hobbies should be protected, nor my likes. What I like is for any other hobby and like to be treated with the same level of respect. And vice versa. This is not because I think my hobbies are superior or more righteous, but because we all deserve that level of respect.
I acknowledged in my OP the good that those series have done by raising awareness and I'm not bemoaning that, but I think expecting better from writers, actors, actresses, producers and entertainers is not something we should shy away from. Is something we should demand.
