To those not familiar with the hilarious Fern Brady: there's probably absolutely miniscule overlap between people who like her style of comedy and those who like hacks like Iglesias and Dunham.
No clue about Gilmore Girls fandom overlap, though.
That's like saying "oh, you like gummy bears? I bet you also like pasta carbonara!" 😄
Gilmore Girls is popular in autistic circles because of Paris (the character). She is never specifically called autistic but, like Abed in Community, her character is a very accurate representation.
