Nothing he said hadn't been presented as medical fact. At that time Dr's believed that transmission of the disease happened through swapping any body fluids, including spit. So, the joke where he talks about a chick partying with her gay friends, gets a goodbye kiss on the lips and brings AIDS home to her husband was something that was considered medically plausible in 1983.
If you're feeling some type of way about the jokes because someone close to you has AIDS or died from it then just say that shit. FWIW, however, in late September of 1989 my then favorite uncle died from AIDS in Dallas. I was given enough time to go to my senior homecoming dance and was scooped up by my family from Saginaw immediately after I got home that night to drive down to Dallas to get his affairs in order and for the funeral. Shit had me fucked up 'cause earlier that summer he came to Saginaw to visit my grandmother. He was so skinny that I didn't even recognize him. Nobody told me what what going on and it had me so fucked up that I never spoke to him the entire time I was there. He was a GP doctor and had to let his staff take over his clinic because his appearance had his patients shook.
AIDS affected my life personally... In the 80's... And I STILL laugh at them jokes. I laughed again when I re-watched it yesterday.
