When we learn words weren't meant seriously, they shouldn't be taken seriously. It doesn't matter how horrific or morbid they appear to be. Even some jokes by mainstream comedians can appear pretty appalling on paper. That's why context and intent matter, and jokes are jokes, even if they aren't to your taste. People have been expelled and had their education derailed because of jokes they made semi-privately on the internet, off campus. If you support that, your sense of empathy and moral maturity isn't as developed as you'd like to believe.
