Some of the things that points out "this is ra**" is for example; the countless times sanho said "stop it", he tried to run away but talk literally pinned him to the ground making him unable to move, after sanho's dream we could see that he was disgusted, sanho never agreed to having s** in the first place, tak just started it. And one of your arguments for this not being ra** is that you can't know the person who's raping you. (This is in one of your other comments) this is completely false, you can get raped by anyone in your family, friends or at a workspace. The rapist does not have to be a stranger.
