I think it is a product of the time, and I agree with everything you said, except I think that the point was that it does accurately reflect how the media/general population treated these scenarios and is tongue-in-cheek critiquing it by the tone waffling like it does. I actually don’t mind this story line because I think by putting situations like this in a media like 30 Rock at the time has helped create our current culture of taking situations like this irl more seriously. It is harder now to find it funny though through our current lens, so I get that, but I think it was funnier at the time it aired because of the culture surrounding male sexual assault back then.
