There was that time the Joker tied up Batman and Robin and filmed a beastiality porno with a goat. It was referenced in canon in the Penguin miniseries in 2011.
And I wouldn't say that it's disrespectful for someone to be afraid in a very clearly compromising situation. It's like people consider victims of crimes to be inferior to other people. What about the covers that feature Batman as a child surrounded by the corpses of his parents? Isn't that worse?
