AIDS
I think this movie might be a comedy about AIDS. The non-imnune body, the prohibition of sex.
1Jimmy cnnot do a lot of things but specially he can not have sex.
2And what about the cult? Many cults in the 80 related AIDS pandemy with The End of the world and that such of things.
3. The freak show. The first people who contracted AIDS were regarded as condenmed people, non-citizens, etc.
