I feel like that’s part of the show’s appeal and dichotomy. Like, Sarah Lynn’s drug use. Obviously drug addiction is a very real issue, but also having her snort drywall doesn’t negate that fact. Or Bojack’s abusive father asking him if he’s go around the horn or take the panama canal like a democrat. The way their struggles are portrayed doesn’t make them (or Sarah’s death) less than just because there are jokes interspersed throughout.

It’s just gallows humor. At the end of the day, Bojack Horseman is a comedy show that doubles as a character study and happens to touch on heavy topics sometimes.
