Slightly different perspective.
Firstly I do get the impression that your daughter may be acting as a quasi surrogate husband when your husband is away. Not sure whether that's good or bad but it is a factor in your dilemma. You have allowed her to assume non-child status in part of your relationship.
Anyone else spot the irony of those posters who used swear words when condemning your decision to allow her to see this material ?
Eleven years old - so secondary school at least on the horizon, first teenage hormones kicking in, dissecting frogs and worms to come in science class, a history syllabus that will be knee deep in gore at several stages, and if you think Family Guy is un PC you should check out the average playground.
I don't think you will have done much harm by letting her view this material. I've never heard of anyone blaming inappropriately early exposure to stand-up for their life going off the rails and this does sound like quality time.
Personally on a judgement call I'd say "not suitable", particularly Family Guy.
But I think I can comfort you by saying that you are likely to mess up as a parent in far worse ways than letting her watch inappropriate comedy shows.
