<human>: Can you condense the text into a few key points?

I am f23 and attend a community college (I graduated from a university and majored in Politics, but that didn't get me too far so I went back to school to get more specific skills) and one of my classmates f26 is incredibly rude and ignorant. 

For example, she made a blatantly racist comment the other day, and when I confronted her about it, she seemed to not even realize that it was wrong. But she has this hatred, and I mean HATRED, for hookers because of issues with ex boyfriends cheating on her with them. 

This hatred goes so far that she says she supports a local murderer who was recently found guilty for killing a ton of prostitutes. She doesn't care that most of these women are forced to do it and are in pretty bad places in their lives and this is probably not their dream job.

I've tried telling her how awful this is, and reasoning with her that prostitutes are human beings too and maybe she needs to pick better boyfriends, but nothing will stop her almost weekly rants about killing prostitutes.

What can I say to her next time she brings it up to drive home my point??
<bot>: classmate wants all hookers to die and I want to make her stop talking about other human beings as if they were disposable.
