I think a second core problem with BBT is that it really plays into the "trappings of being intelligent" - which is not how most intelligent people actually are. There are a TON of "signalling" devices, for example liking comic books, or having thick-rimmed glasses. Now, I'm not a physicist (chemist/biologist) and we may be more "down to earth" but I don't have a single scientist friend who HAS THE TIME to do a lot of those things that maybe in high school geeks/nerds did a lot of. I don't know anyone who plays D&D anymore, I don't know anyone who goes to Comic-Con (I'm in San Diego). We do stuff like - go hiking; I'm obsessed with social dance (where there are, incidentally, tons of engineers and scientists); I had a lot of math majors friends from college and of the ones that did math PhD programs, they wound up: climbing rediculous spires in red rock country, supermarathon running for fun... And one, after getting his PhD, joined the Navy and entered its pilot training program (he would have become a fighter pilot but there were no fighter billets available).

So, what bugs me about BBT in addition to having really awful people (watch "BBT without the laugh track" on youtube if you doubt it), is not only that it perpetuates stereotypes, it perpetuates really dumb stereotypes... And the life of a scientist, I think, swings from incredibly boring times in the lab, to super-exciting times in the lab, to "relatively normal social life" outside of the lab, except that that last one gets a lot less time, since, we're in the lab all the damn time.
