I agree with this. Insofar as you're supposed to laugh at the characters, I think it's true of pretty much all sitcoms. Sitcoms are almost always about broad stroke "laugh at yourself, because you are funny" kind of stuff.
But more interestingly, often people who hold up this argument are fond of bringing up The IT Crowd as a counterpoint to BBT on this front and... I just don't get it. The people in IT Crowd are basically awful human beings I can't sympathize with, in spite of existing in a vaguely similar world as they do. The characters on BBT feel much more sympathetic to me. They're mostly trying to be good people at least.
