I agree with Rudy.
However, Dan’s concern is valid and this is why Sierra offered players the option of playing a censored version of the game which omits that scene entirely. Roberta has been asked about this scene numerous times and says that she doesn’t regret the scene because it fit the story so well.
If the scene were that offensive, I’m sure Phantasmagoria would have received the Ao (Adults only) rating which is a higher rating than M (Mature).
