I'm in the "nerd blackface" category of people when it comes to this show. I've seen a few episodes and in the ones I've seen I didn't get too much laughter from it myself as it really felt like we're supposed to be laughing at these guys because "ho ho, nerds are so awkward and goofy!"
I've spent my entire life being one of those people, I'm not going to contribute to their mockery.
To me it doesn't feel like mockery because honestly i've met guys like this and to a degree i am like that which is why i can relate to the characters and why it doesn't feel that made up (though i was never a full blown nerd who buys costumes and display figurines).
I think if someone can't take some humor at his own expense they should take a step back and see things from a different perspective because we all mock every cultural group.
Jocks mock nerds and nerds mock jocks, if it's a good joke i'll laugh and that's all i want from this show.
I don't take it personal because all the guys (even Sheldon) are decent guys who will help others no matter what, they are passionate about their jobs and private interests and the humor comes from a place that's not mean spirited.
Who amongst us who has full blown comicbook/toys/Comic Con attendee friends didn't recognize character traits shown in the show that fit their friends? They may be exaggerated for comedic purposes (i seriously doubt there is someone this clueless as Sheldon when it comes to social conventions without some form of mental issues like the often denied Asperger's syndrome) but i don't mind and laugh which is all the show is trying to do.
But, again, for me it seems like we're supposed t be laughing *at* these guys because they're nerds, social misfits and interesting in uncommon/main-stream things.
And is it really "good" to laugh *at* these guys because they're smart, into comic books and Trek?
I watched an episode where they're going to a Star Trek convention dressed as characters from TNG. The stop at the Vasquez rocks for a photo-op and while doing so their car gets stolen so the hoof-it to a nearby diner in order to come-up with a plan.
So, they enter the diner in Star Trek uniforms and make-up and are immediate treated like outcasts and misfits by the diner's patrons and staff. And because "ooo they're nerds. They're smart but can't deal with reality at the same time!" the solution one of them comes up with for their rescue is to call his mom to come pick them up (or give get them a rental car or something.) Again, this is played for laughs and not for a practical solution to their problem, showing that they're such misfits they have to call mom when they're given something they can't handle.
Sorry, I found it sort of offensive. Not angering-ly offensive just, "sheesh. this is the shit I went through growing up" offensive. People laughing at me because I'm not like them.
In the same episode their girl friends/the female characters try and to understand the guys better and their want to go to to this convention so they decide to try reading comics. They go to a comic book store. Where. ooooo, guess what? A trio of good-looking girls walk into a comic book store and all of the regular gawk and awe at them. "Pretty women! In a comic book store!" That *never* happens! Isn't it funny how these outcasts act and behave when confronted with pretty women in their regular hangout? Ha. Ha. They're nerds!
The "funniest" thing for me in the episode is when the girls read the comic they bought, as well as some of the comics belonging to the guys, they get into a nerd-like shout-fight over Thor's hammer, Mjolnir and what it means that only he can pick it up.
Leading to one of my more favorite questions of the concept, whether or not it's possible to pick-up Mjolinir by proxy. (Pick up Thor while he's holding his hammer.)
But with the guys and treatment of the people at the LCS? I dunno, I don't think it's right to laugh at "my kind."
