"These aren't real nerds! They make us all look dumb!"
Other than Sheldon's quirks, I've always felt like the characters were just like my friends and I and this sentiment that permeated Reddit always just felt like people who very much are like Sheldon were the ones taking the most offense at the show.
Later seasons really flanderized some aspects of the characters, but I always fondly remember one scene where The Gang is assembling a new TV stand for Penny's apartment and someone questions the airflow it offers. So they immediately start designing a water-cooling system for her TV.
While they have done some pretty unsavory things involving Penny being the butt of many jokes that border on sexist, I can't think of a single example of homophobia from the show.
This reeks of projection. You can’t dislike this thing I like if you do you are like that weird guy that is sexist on the show you don’t like!!!
You sir sound like Sheldon.
