I think they weren't prepared for this episode and it shows.
Honestly I didn't mind that they covered the topic. It seems to be a pretty big thing everywhere right now and I honestly don't have the time and energy to engage with it myself which is why I'm happy Stan and Marshall got to do it for me.
On the whole I think the sentiments weren't all that bad but the thought process was a little overbearing. I don't really like when people want to rigidly define things that are common sense. For instance, if some neckbeard decided to make a "manga" about Japan and wrote about how all the "submissive asian girls" crawled to the mc's cock then nobody would need to be told why it's bad, it's just laughably cringy.
I think the core issue was Jennifer herself. I don't have it out for her like some peolpe did (having looked at the youtube comments for my own curiosity) but she really wasn't qualified or experienced enough to be informing everyone through such a platform. She wasn't even able to take a stance whether it's okay to represent other races/culture in your art work, even though she said she was studying to make comics about black queer women (if I remember correctly).
