It is very common for people to take the depiction of something as an endorsement of it. It's somewhat bizarre; in order to be sure that the writers condemn an awful thing, they all but need them to have a character break the fourth wall, look directly at the camera, and say, "just so you know, we believe that this is wrong."

I like it when it's up to me to gather the meaning of a text, and to conclude that something is wrong; I find it insulting when a narrative doesn't trust me to figure it out. But it is the case that quite a lot of people are insulted by the exact opposite approach. I struggled to understand it.
