Tried to look up the comic’s rating. This site gives it NC-17. Interesting panel shown. The dad says he wanted to be a girl, and dressed up in girl’s clothes. The girl says she wanted to be a boy (says she dressed in boy’s clothes: how can she tell? Did she buy boy’s underwear?) Sounds like the dad was a tranny, not homosexual. Explains why the girl became a lesbian, being raised by a fruitcake.
