Not who you replied to, and Gaiman may be innocent, but we should listen and find out. The “absolutely reasonable assumption” is probably based on his age and how he was raised.
I don’t know how many men you dealt with that were raised with the mindset of “if she said yes once it means she says yes ALL THE TIME,” but some men feel that way. Hell a very famous and still popular movie has “Tell me more. Tell me more. Did she put up a fight?” In the opening of the movie. It seems kind of reasonable to me to assume being raised that “no” is something you have to “fight through” might mess with head.
I’m not trying to justify any actually actions. I’m just saying I would listen to the victims before I dismiss the accusations just because I like the art he makes.
