I did some googling. Here's Lamar Abrams's wiki page with a list of episodes he's done:Weird that they talk about how problematic anime is. I thought that at least a few of them were cool guys because a bunch of scenes from the show are apparently just ripped wholesale from anime. There's way more than the one example posted above.
Also, he's an artist who is talking about "unlearning" stuff. You know, doing the opposite of using years of practice.

Then I did a search for "worst Steven Universe episodes" ("worst storyboarders" got no real results):

Note how more than half of the episodes mentioned were his doing. I think he might want to re-evaluate his testosterone-killing diet.
