Again, I feel like people are over analyzing it. If it's not funny to you, that's fine and normal.
I don't see it as being offensive at all. Family Guy, Simpsons, Rick and Morty, The Office, etc
have done worse ish on TV. Even friends have the same setup as big bang. The character's
quirks make things funny, which is true for ALL sitcoms. ALL. Geeks being overprotective of
a billion dollar franchise IS FUNNY. It happens in real life and people DO react to it in a condescending
manner. The show didn't invent these type of scenarios.
